I have one Super Turbine 300 Transmission that will fit 60's or 70's Buick Oldsmobile and Pontiac. It is the original 2 speed trans that they used in the 60's. It's basically the powerglide for BOP cars. I also have some Turbo 350 and TH 400 cores, early 4L60, 4L60E, GM and ford transfer case cores, Powerglide cores, and Chevy GM GMC differentials too. Call Mike at 209-30four-4557. Check out the "more ads by this user" link. Thank you and God Bless.
