What year car or truck do I look for to find a 700R4 with the correct bolt pattern for a 428 Pontiac engine. I am still thinking about doing this conversion for my 55 stationwagon and using an overdrive transmission to try and get some decent fuel mileage. I remember reading somewhere that some 700R4 have a dual bolt pattern. Iwould be interested in just finding a casing with the correct bolt pattern as I have a couple of 700R4 transmissions on the shelf and could just swap the internals while doing a rebuild.

I bought the adaptor from Trans Dapt...
Thanks for the suggestions. I wonder if a 86 Grand Prix Aero Coupe would have a heavy duty 200 series like a Monte Carlo SS. I will also check out the Trans Dapt adapter. A 200 would make the swap easier as it would be same same length as the turbo 400 that is on the engine now. I want to use the car as a highway cruiser when completed.
