Again, there is a lot of mis-information about this starter. Jerry's 1993 Z28 book (I think 1st edition) had a mistake on the starters on page 71 which I discussed with him when I was looking for the correct L48 starter. He posted a lot about it a while back on CRG and Kurt and others dug in and confirmed the data. Jerry was discussing correcting the data in his 4th edition.
For 1969 the SS350 only, it had 3 starters. The Automatics had the small flexplate so they received 1108361 (early) or 1108420 (late) for both PG or TH350. Because the L48 4-speed had the large flywheel it received the 1108338 starter. 1967 and 1968 SS350's only list one starter for the L48 (1108338) in CRG's starter info:

So Jim is looking for the correct starter. I just tacked on because of the bolt issue.
The 8365 starter (jl8z28) is for a L6 with the small flexplate/flywheel per CRG's page.
