Default 200r4 tranny

Will this bolt into my 1975 Corvette?

200r4 transmission out of a 1986 Buick Regal V-8.

I've done some research and it looks pretty good so far.
I know I need to do something about the lock up converter electrically.
And the Transmission support.
But is this what I'm looking for?

I'm probably putting out less than 300hp.

Ralph

I recall the transmission mounting tailshaft pad is in a different location on the 200R4 compared directly next to a Turbo 350 or Turbo 400 Trans.

You will need to have your main trans driveshaft shortened too.

I don't recall all dimensions tonight.

Check B&M website for more details & GOOGLE too.

Check with PATC trans website too.

Trans from a Buick Grand National & GNX are best 200R4's.
Highly prized by everyone outside of C4, C5, & C6.
