GM OD tranny fit?

This thread is a little beat-up but.........A 4l65e(60e) / 700r4 / 200r4 will not fit without mods. Crossmember, mount, little beatin on the tunnel will be required to make it fit. A Gearvendors behind a 727 is the simplest Auto OD

I have a 4l65e mocked up behind a 6.1 now.

Of the GM trannys in an A body, the 200 is probably the easiest fit. I have done several of the 4l65e conversions in B bodies and have only had to modify the pinchweld at the firewall. (Hammered it flat at the 10 and 2 spots.) My understanding is that it's a bit more work to put one in an A body.
To be honest, I really like the way those trannys shifted over the 518.
