I'm looking to replace my 4+3 trans out of a 85 for a ZF from an 91.
I have been told that it will bolt up with little modification.
What is the model number for the ZF six speed?
Thanks. JT

Interesting...before you start spending $$$, have the person who told you that spell out exactly what little modifications are required...

Not being a smartass; I'm a machinist...I can spend days making little modifications...

Thanks for the info.
I hear you rich. I think it will bolt right up but may have to cut alittle where the shifter goes.
