I came across a cheap mazda spoiler that is missing some mounting hardware (most of it). the parts catalog is not very clear (bad scan, etc.) so I was wondering if anyone had any more detail on the mounting process etc. My spoiler has some of the studs, but is missing others. a couple of the studs appear to be JB Welded (which is OK given what I paid for this thing).

The parts I'm interested in understanding better are circled in red in the attached image. There appears to be a T-slot mount for the two corner studs, but I can't figure out what they would look like (one of the T-slots is still present, but the other is gone. A

Any help (pics) would be of great help.

Thanks.

If I remember correctly there are two screws that mount on the forward sides of the spoiler, they screw into plastic plugs. The two corners have weird plastic nuts that attach from underneath. Then there are two regular 10mm nuts that attach to the middle points on the spoiler, both attaching from underneath. Hope this helps.

RED1990GTU is correct. The "weird plastic nuts" he's referring to is the part marked "51-RS4" in the FSM diagram you posted. It's a white plastic clip with a rubber gasket on the bottom side to keep water out. I've never figured out a way to remove/replace the spoiler without breaking these somehow because they tend to get pretty brittle with age. You can try to squeeze the wings from inside the hatch, but I find they usually end up snapping apart. The current part number is FC17-51-968. You need one for each corner, assuming you plan to mount the spoiler on a car that already has the holes drilled in that location. I paid $4.22 each for them from Malloy Mazda last month.

Here's some photos so you know what they look like:

har har har... i didnt even bother to ask on the forum until seeing this. anywho.. i just sanded down a red stock spoiler, primered and sprayed black. it looked awesome but i could of done a better job. i was rushing myself to get it on my 7. i already had like the nuts on just so i dont lose them, 2 10's and 2 12's i believe. the front screws i just drilled a small hole for it to mount onto the chassis. after finishing, it looked good and still sits nicely. and just to make sure water doesnt get through onto the metal and leak through to rust. my friend spray a little rubber undercoating spray around the hole.

Thanks, the pics help a lot. Also good to know they aren't too damn expensive. I'm always afraid to step into a dealer with a part request for this baby! I'll be pricing the caps too. Guess I don't care what color since I'm probably going to paint the car a different paint than the sunrise red it is now. It'll still be red though

I bet I'm just not versed in reading the parts catalog, but....

Page 3- K 7 of parts catalog:

The pic shows just one of the clips, your post says two, the catalog states QTY 4. Could it be that there are two methods to attach this? One for using the clips, and another for using studs? One method for user installed, one for factory installed??

If you look at the picture, it only shows one of the clips (pass rear corner). The drivers rear corner shows some type of stud (68-865), but in the QTY column, it only calls for 2.

And while I'm at it, whats the diff between parts pictured in a rectangle (i.e. 51-964A) vs. those not in a rectangle (i.e. 999-60-600)? Seems the ones not shown in a rectangle don't appear in the parts list on the right either.

I'm a little puzzled by that diagram myself. I've taken the spoilers off my '90 and '88 GTU cars and both had the same hardware arrangement. You need two (not 4) of the white plastic clips; one for each of the rearmost corners. Could that 68-865 part be the metal collar that is embedded in the spoiler that the clip slots into? I don't know.

Were some spoilers dealer-installed on cars that did not come equipped with them from the factory, which explains the different hardware options? Maybe. I'm not aware of that myself.

I think the items in a rectangle are considered "parts" in the Mazda catalog while the items with just a number are considered "hardware," like fasteners, nuts, etc.

Well, I'm putting a spoiler on an SE that never had one, so my biggest issue is I don't know what hardware I'm missing. I'm like you, the diagram is a bit confusing (as well as blurry).

So there's a collar or sleeve thats inserted into the mounting holes on the car body? Is there something in all holes, or just the rear corners? In looking at the spoiler, there will be 8 holes I'll need to drill:

2 - front tips (smaller)
2 - rear corners (larger)
2 - in between two above (larger)
2 - in between the rear corners (smaller)

I could drop into the dealer with that page from the parts catalog and see what they say. Maybe there's a mounting kit that includes what I need? This dealer is a bit snob (nice way of saying *******). Last time I went in to order something for my SE, they treated me like a second class citizen. I'd never let them touch my engine, that's for sure.

There are only six holes in the body for the stock installation:

(A) There are two at the front "tips" of the spoiler. On the stock installation, you have a metal screw which goes through the spoiler and is retained inside the body by a plastic plug. I'm guessing that is the part number 51-953B from the parts fiche diagram, though I've never had to replace those in either of my cars.

(B) Then you have the two plastic fasteners in the rear corners of the spoiler from the photos I posted above. These twist and lock into a metal collar that is embedded in the spoiler itself. The other side snaps into a blank hole in the body. There is no corresponding collar or other hardware on the body of the car, just a bare hole.

(C) Finally, you have the two threaded studs in the two inboard "legs" on the back edge of the wing. These studs are embedded in the spoiler and are attached to the body with one 10 mm nut each. Again, there is no hardware in these holes either. From the parts fiche illustration, it suggests there is a retaining bracket of some kind (51-9MX and 51-9LX). Neither of my cars had such a bracket. I just went outside and looked at it. There does appear to be a reinforcing metal plate bonded around the area of these two fasteners. Do you really need this? Probably not. I don't see it in the parts diagram anyway. For all I know, it is already on your SE.

I've never seen anything between (A) and (B) above. You mentioned needing to drill two more holes, but I don't think they are needed for a stock installation.

I'm wondering if Mazda changed the hardware sometime midway through 1988. What I'm describing is the way the S5 spoiler is attached. My '88 is a pretty late production model with a build date of August 1988. Therefore, my experience may be limited to the S5/late '88 version of the spoiler. Maybe the early build date '88s were different?

All S5 spoilers had the "Mazda" logo embossed on the underside whereas the '88s had it on the upper surface. Where is the logo on your spoiler?

Here is a pic of the underside of the pass side of spoiler. It does have a stud between the tip and the corner. It could very well have been "user added" but it doesn't appear to be. The black in the pic seems to be sealant or trim adhesive. But, since they are there and it would help hold it on better, I'm gunna use em

On your logo question, mine is on the top side.

That does look OEM. I guess I didn't remember it right. It has been a couple years since I last had the spoiler off. I didn't remember having to remove any interior trim to do it, but then, I do remember it was kind of a big project.

If you need to replace your antenna mast, make sure you do it before mounting the new spoiler because you have to remove the spoiler to get the upper garnish off.

If the Mazda logo is on top, I'd guess that came from an '88 GTU or '88 TII.
