Even though several sites say that is the correct starter, I have been suspicious of that part number from your first post. Suspicious that the vendors-for the vendors have got the wrong part number on that starter. I noticed that on Ebay and other sites selling that part number, that the application is way up in the 1990's. For BB V8's. That is highly, highly unusual. It makes me think that being "new" that they are using a pinion gear or solenoid or something for the 90's era flywheel or ???
Also see starters for 60's GMC straight 6 cylinder. Could be a mix up just about anywhere in the logistics. Just getting that off my chest.
