I'm looking to replace my stock 3 speed manual in my 71 bronco sport. I'm looking for an 88 - 93 C4 AOD tranny. Does anyone know where I might be able to find a good core? I've found I can buy an adaptor kit to make the tranny bolt up to my Dana 30. Has anyone done this before? If so I would like to know if you have any recommendations. I plan to go with a 4.56 gear and 35" tires and put the tranny behind a rebuilt 302 putting out around 350 HP. I welcome any comments on this project and any help finding a tranny would be much appreciated. I'm in TX between Dallas an Houston.
