I'm going to be receiving a ZF5 out of a 90' F250 gasser - I would LOVE to swap out my T19 for the 5 speed, I *thought* there was some issues swapping a gasser ZF into a diesel - will this bolt up to my 6.9IDI or will I have to make some modifications?
Are there different gear ratio's between the gas and diesel 5 speeds?
