I guess I will try the auto starter. Here is the deal. I have my mangusta engine on an engine stand that I normally use for 351c engines and you are right. When I tried to install the starter it hit the bump on the 351c bellhouse and broke the starter tab. Like a fool I threw it away. I now am using the mangusta bell housing.
This early mangusta has a lot of strange parts on it. You could tell that the engine had never been out of the car. But the engine is a 302 with a different number 302/0083. I can only assume the factory install this different numbered engine. Not sure what was going on, but the engine had different ford internal and external parts like 289 hipo counter balance, hipo flywheel and harmonic balancer, hipo carb and modified oil pan stamped by detomaso.
Steve, thanks for your help
