I have said this in many threads before. I would not do such a swap unless I could do it right and the only way that I know that I can do it right is to have the entire donor car setting next to the recipient or at least nearby.

To do it right will require MANY more parts than just the pedal assembly and transmission. I can list the main things that are different on these cars and I'm positive that the list would forget something. There are lots of parts that you won't think of unless you are in the middle of the project.

Things that will be required from the donor car are the driveshaft(different length), flexplate(different), pilot bearing, flywheel, clutch, pressure plate, throw out arm, throw out bearing, slave cylinder, master cylinder, brake master cylinder reservoir, speedometer cable, possibly the speedometer, shifter, shifter wood trim plate, shifter rubber boot.

That was a partial list of REQUIRED parts. Parts that are different and should probably be changed, motor mounts and some other pieces that I can't remember.

I am NOT discouraging you from doing this swap. I think it is the best thing that can be done for a 124 car, what I AM doing is encouraging you to get the whole car so that you can do it right and not have a cobbled up jerry rig.

Good luck,
