Sam if you have the motor off out of the car it's alot easier. All you have to do is get a paperclip, extend the starter drive without the motor spinning and check the clearance in 2-3 spots. If off, Titlon sells shim kits with there starters. I know that you will rip up the drive with a big motor if it's out. This starter is strong enought to engage the motor and drive the car into a trailer. I have done this when I was alone. The spec is .035" not .350" I think you forgot the .0
The bell housing was centered on the crank before you started these measurements? Has long as the drive covers the whole tooth on the flywheel you will be OK. I think the first time I did mine I had to take shim out to fit. I will see if I can find the info for setting up. This is why I leave the starters, flywheels, and lakewood bell housings with the same motor for life. This little crap is a pain, but if not done right, you will wear out parts fast. Sam sent me a private e-mail to call you at tonight see if we can fix this for you. Rick L. or call me 732-254-3536 est. after 7:00pm
