Hi, Have done the VIN Decoder thing before. 1978, Dearborn MI, Mustang 2 door 4 passenger hard top Ghia (Vinyl top has been removed), V8 302-2v 139hp. Spoke to a local mechanic today who told me to toss the M97LE trans and replace it with a standard C4 unit. Told him that the research I had done so far said that the bell housing was altered in some way from a standard C4 and may also not fit. Not sure if this is actually the case or not. No examples locally to check on.
