For what it's worth, I had to change out the dinosaur starter on the motorhome last summer, keep in mind it has header's on it so it is not an easyjob to change, got a mini starter from a 80's(i think) dakota tried it and it would not fit for crap, hit the block and the terminals were in the wrong spot' 1 mounting bolt would not engage the thread's ,,took it back to Car Quest and exchanged it for a 90's full size 360 truck and fit like a glove, can even snake it thru the headers to swap it out, and it looks just like the one on the race car that I bought from Mopar Performance years ago, maybe you are using the wrong style.
