Re: aa QUESTION
All should be OK. You don"t say what year, or what trans the buggy has - Differences are that the 4 speed trans clutch disc was a little larger diameter, and the truck pressure plate had stronger springs - but all should interchange, and work nicely in the buggy.

Re: aa QUESTION
isnt the only difference is the clutch disc i maybe 1/4"-1/2" larger in diameter? for a doodlebug you wont ever notice a difference between the 2.

Re: aa QUESTION
As I think back ,the throut bearing hub is different in the 4 speed than the 3 speed. (was in my late 29 with the 4 speed ). If I'm wrong let me know
because my clutch has always been high to release. Mac....

Re: aa QUESTION
They both use the same flywheel and the pressure plate will work.

Re: aa QUESTION
You need to use the shorter AA throw-out bearing carrier and the AA bellhousing.
