SST/Keisler Automatic OD Fitment

I just finished the install of the significantly smaller 200R4 in my '68 Barracuda, and I had to modified the driver's side cross-member, but not the floor itself. It is now significantly stronger than it was stock, and it's tucked up in the tunnel with great driveline angles.

I would imagine that most of the crossmember would have to be removed for the larger GM transmission that takes more power to drive.
