The computer is from a 92 bronco 5.8/e40d. u may be right about the 88 trans, i know it isn't the E40D and i do have the trans from the 88, it has a small oil pan.Do you know what trans was in 88 or was there more then one. Good point on the flex plate. Do i only use one from a 5.8 e40d or is there others.What about the converter? do i use mine from the 302/e40dor do i fine one from a 5.8 e40d?
