Dave, I am curious now. If your Pace car is a 4-speed, then it should have the larger 168 flywheel (11" clutch), which the 8338 starter fits. If you were able to install and use the 8361 starter, your car must have the smaller 153 flywheel (10.5" clutch). Hmm, if it mounts and runs, did the nose get swapped? I just looked at the 1970 HBC 8338 starter ($450) and it has a nose with the long/short bolts (strange).

Anyways, I have a 9B4 8338 starter I bought from Jerry. But its a bit early for my May/June SS350. If you run across a April/May starter, maybe we can do some horse trading.

As to the bolts, the repro ones I found years ago look similar to the GM ones, but are a bit long. I had to use a washer to mount it, but that's fine. My car is not on the road yet :( . I just have to keep my eyes open for a more reasonable GM one at the swap meets.

Kevin,
This Post put me down a rabbit hole, but I managed to climb out today.

I just purchased (2) two 1108338 starters, dated (9 B 18 and 9 C 4) wasn't sure of which date I really wanted for my 03D Build so I purchased both....lol

Okay, as to my Pacer it has the #733 Flywheel, which is 11" (168 tooth) and 621 Bell. My car is also not on the road yet and not together.

The starter I have 361 has the straight bolt pattern with the aluminum nose, which is for the smaller flywheel (153 tooth) and not correct for my car.

Being that I was told it was the correct starter I was going to change the nose with the diangled / staggered bolt pattern one. I never did because I wasn't sure if it took the aluminum staggered bolt pattern or the cast iron staggered two hole nose.

The two starters I purchased today have the cast iron staggered 2 bolt pattern.

168 tooth or the easy way 14" diameter.

Sorry, 168

Dave, glad this post helped you get the correct parts before you tried to assemble it and found out it was not going to work :)

If you could PM on where you bought the starters, I would appreciate it. thx
