Auto to Manual? (Sort of)

Every early slant I ever pulled had a factory installed pilot bushing in it. So before you start looking to get one why don't you remove the automatic trans flex plate and have a good look at the end of the crank.Take a close up photo of the back of the crank and post it. Lets see what you have. As far as getting a bushing if you need it,they can be had at any good auto parts store for under 10 bucks
