My '73 el camino has a Turbo350 transmission with a floor shift.
I have a 700R4 Transmission which is in better shape than my T350. Plus it has an over drive gear.

I was wondering if anyone can help me out on the swap. I can't find anywhere that shows me size specifications for the two transmissions. I need to make sure the 700R4 will fit. I need to know if I can use the same crossmember or not. I also need to know if I'm going to have to cut my driveshaft a couple inches.

Also are their any suggestions for doing this?
