The starter will physically fit. The only real difference between starters from 79-88N/A is the size of the starter drive gear. It became larger somewhere along the way, I do not know the exact year. Look both starter drive gears over, if they appear to be the same, it should work. The size difference is rather easily seen.

thanks, as the doctor said, in an earlier thread, is that there should only be two wires. On mine i have the main power, secondary power that runs to the little tab, and a third wire that runs from the same harness as the little tab and runs to the other post on the selenoid . Something wrong here?

i remind you that i may have hooked it up wrong along time ago and i keep having to replace the third wire im talking about like its overheating, yet the car wont start without it.
almost like its bypassing the selenoid or something.

yeah there must be something fucked. As for the orginal starter i took it out today and had a look, appears that the actual problem was that the exiting electrical post on the selenoid is loose inside the selenoid itself, so that no current could be created. I figured this out when i put power to the second post and the starter turned over. So aslong as the new sa starter fits, i think im good to go. Btw, i think why "replacing" the extra cable was working is because it would turn the exiting power post, causing it to touch somewhere against the internal contact, just enough for it to arc and start. Thanks.

see
see alot of posts asking about parts interchangeabilty of parts between years.
Your best resources are the following.
www.mazdatrix.com
www.rockauto.com
www.blackdragon.com (get their catalog)
www.cskauto.com
www.napaonline.com
www.autozone.com
www.mazdaatuoparts.com
Then there is the factory parts catalogs Via link from trochoids homepage.
That's all you have to do is look up the parts and compart parts numbers for years.
Mazdatrix is probably the easiest to do.
And yes their is interchangeabiltiy that is not in the parts catalogs.
Basically all 79-85 M/T starters are interchangable.
80-85 alternators are interchangeable
Electronic dist are are interchangeable for all 79-85
Front mount oil coolers are interchangeable for all 79-85 whether replacing existing one or upgrading from Beehive.
Radiators from 79-82 all interchange. Can also be used in 83-85 models.
There are some small mods when doing the above but everything can be found by using the search tool. All of these interchangeability parts have been covered many times over.

As stated before, sometime between 79 and 88, the drive gear was changed. I do not know exactly when. Examine the drive gears, if they look the same size, then you're good.
The difference is easily noticeable, when they are side by side.

I have not tried this, so I cannot say.
I can say that I had to change the starter after swapping an 85 12a into a 79. 79 had the small gear, and that starter wouldn't engage the flywheel of the 85 engine. Only other starter I had handy, came off my 86, and had the larger gear. It worked.

starter spline numbers, on the driven gear.
7 is sa
8 is 81-83
11 is 83+
Thats what i recall anyways.
I just took it out and its an 8 so im looking to find an early model FB starter. Although the trany on my new sa says FB on it and it also is a remaned engine so it very well could be an fb motor and trans. Btw, i have also found a thread that says that the 8 and 7's will work in either trany due to the characteristics of the starter teeth themselves.

Ok, now I understand what you were asking.
the 7, 8, and 11 tooth gears sound right to me. As does the 11 tooth gear being 83+, since the 83-88N/A all use the same 225mm clutch.
One odd thing, though. When I swapped the 85 engine into the 79, I had to replace the flywheel ring gear on the 85. The ring gear was the same size as the 79, yet the 79 starter wouldn't engage, even though the trans was still the original 79 trans. It was a move of desperation that led me to slapping the newly rebuilt starter for my 86 on it, which works fine. Just left me short a starter for the 86......

yeah i think it actually has something to do with the bellhousing or the location of the center of the driven gear on the starter in relation to the bolt holes on the bellhousing itself. Anyways, just rambling. Il see if it fits tomorow.

ok i was wrong,
SA is 7
early fb is 8
Late FB is 9
i opened up a late model fb today and it had the 9 spline, and then i opened the 82 and it had 8. luckily my SA has an FB starter and flywheel and all that good stuff so it bolted right in. I experimented with the third wire and the car runs exactly the same with or without it. So it must be useless and probally there for no reason. ON the remaned engine i found that there was one on there too. But they could have done the same thing and just assumed the third wire was for the starter where it could have been for something like a sensor on the bottom of the block. Although im still confused im sure now that the third wire on the starter is usless. Thanks for the help.
