need help with my 4 speed tranny

How much power are you going to be putting through this trans? The O/D's are not known for their strength. It looks like maybe you would be better off to go to a swap meet and pick up a complete A-body 4 speed with a bellhousing and linkage because you're going to need a different bellhousing anyway and you're going to have to either buy linkage or make it.

Here is a link to the B/E body trans conversion to A-body. http://www.bigblockdart.com/techpages/abconv.shtml
