I am about to can the C4 on account of noisy operation and I have a T5 5 speed laying here from an 84 Mustang GT. I have everything but flywheel. I have read that the mounting pad for the T5 is a bit lower than the automatics. How much lower? Im going to fabricate my own Xmember from the existing one but I dont know the exact spec on how much to lower the mounting pad. Anyone here know?? Aftermarket Xmembers for this conversion dont seem to be available for the FS car.

Thanks,
Tony

The vehicle is a 78 LTD2 302. Im trying to figure out if anyone knows exactly how far I have to drop the trans mounting pad to properly accomidate the T5 and maintain current correct driveline angle.

I figured the spec change would be the same in any C4 vehicle made to accept a T5.
oddly enough, Im actualy looking forward to doing this swap. Thanks for anything you have on this.

I am going to say that you are going to have to install the trans and then hold it up with a floor jack to determine the correct angle and then fab the crossmember and insulator to that determined angle.

I would first determine though that the current angle is correct due to trans. insulator fatigue and rear control arm bushing aging.

Everything under the car is tight and in excellent shape, even the trans mount. The current driveline angle at the trans is almost non-existant so I ASSUMED it to be correct based on the fact that everything is bone stock and in almost new condition.

I guess I can measure the existing angle and fabricate the Xmember to maintain current angle once the trans is in, as you suggested.
I was in hopes that there was a simpler way but this will make it an interesting project.
Thanks for the suggestion. It does appear to be my best avenue at this point.

Thanks for the tip.
