a500 or 200r4 ?

No matter what transmission I use, I will need to make an adapter plate. So using an a500 or a 200r4 does not change the adapter plate problem..

The A500 will bolt right up to a small block, and the OD section spins all the time as mentioned.

If he needs an adapter plate no matter which transmission, sounds like he's using a slant or big block
