Hey, my father wants me to put a t56 in his 455ci 76 Trans am, there is a few companies such as American powertrain, Hurst drive lines and silver sport transmissions that offer complete kits. he got a quote from sst, includes absolutely everything. I'very read several good reviews, anyone dealt with them? From what i'very read they'very purchased Kiesler and are doing things right, great warranty and customer support.
