Sourcing hardare

Last year I picked an 89 FC. The owner had begun stripping the car to convert it to a racecar and changed his mind. Fortunately, I have almost all of the parts but no hardware to put it back together.

Does anyone have a favorite site or resource for ordering replacement nuts and bolts? Not a lot of part outs in my area to take advantage of.

BelMetric. Look for JIS/reduced head fasteners in yellow plated zinc such as this:

I used Belmetric JIS for the suspension parts besides rear the bolt adjuster: https://www.google.com/search?q=rear...t=gws-wiz-serp

For the front area and similar, I bought Amazon stuff.

Rexka M6x1.0 with captive washer 25 mm 15 mm Maybe 20 mm Some parts like the top front bumper take a M6x1.0 10mm bolt without the washer in black, much harder to find.You will need 4 or so of the ones with giant washers for the flaps in the front well.

The bumper cover and brake ducts area clips and some screws came mostly from the Auto parts store. Any screw for the fender liners that screws to plastic will get a captive washer with a metal fastening thread. Just be careful to get some with a blunt tip and short. Some of those poke through to the wheel well. That would take some skin off to bump into one. Not to mention your wiring.

The front fender ones have a washer of sorts in M6x1.0 but have a washer that is part of the nut, not a captive spinning washer. The The captive nut ones should work though.

Get yourself a good M6x1.0 tap and some anti-seize.

You are missing your adjustable stops for the pop up lights.

You will need a bracket for the front of the front fender to bumper cover that has about six M6x1.0 studs. With that about 6 nuts with a built in washers. I bought the non-spinning type, similar to stock.

The front bumper and mounts are M12? You might want to go buy a cheap gauge set to figure it out. I bought a full cheap tap/dye set, they came with it. I went through two M6 taps on my project.

Mazda has most of the fasteners too, if you get stuck, its expensive but its there, which is nice. also you could go to a junkyard and any Japanese built Mazda will be full of the same hardware
i like to google the Mazda part number and then you can usually come up with a picture, and then Belmetric or usually has something close enough.

and then third, the Mazda part number tells you the size of the bolt, which is super handy.
for example, 99796-0816
the 99 tells you its hardware, bolt, nut, screw, clip, etc
796 tells you what kind of hardware, and the list is really really long, best to google it.
08 is the diameter, so this one is M8, Mazda uses JIS standard, so its going to be a 1.25 thread.
16 is the length, 16mm
and there is no letter at the end, so its going to be a gold zinc plating, B is a dark zinc, c is chrome, etc

so 9979-60-816 is an M8x1.25x16 bolt in gold zinc.

That is super handy info. Is there good links for looking up part numbers? I kind of have been using whatever comes up in the first few search results
