Alright, I did all my suspension work at the same time. I put in a 8pt cage, subframe connectors,90/10 front,50/50 rears, Eibach drag launch spring kit with air bag. Ford racing uppers and Lakewood lowers, non adj. It has Convertible motor mounts and a stock transmission mount. I have a UPR drive shaft loop, just to give you a idea the drive shaft you can put almost a finger between the top of the loop and the driveshaft. I have beaten the tunnel with a hammer to see if I can fix it. Driveshaft is hitting in the center and the end of the driveshaft. Not hitting when the car is still, just when you launch it and shift gears under full throttle. What is up with this. Thanks for any help. Scott

Its probably just placement. Can you move the loop back a bit to give you more clearance above the shaft?

That's going to help me. The loop is were is needs to be. Not hitting the loop at all just under the car. It is hitting the tunnel and the right side towards the top of the tunnel. , not the loop at all. Loop is 6'' away from the yoke. you think it might be cause the convertible motor mounts. The motor would be lower, transmissin would be faceing up more? I'am lost

You need to put a snubber on it to stop the rotation of the differential?

Pinion (sp?) Angle? Are you at -3deg? Check your angle that could possibly be it.

Without seeing it that would be my guess! Do you have adjustable Upper/Lower control arms?

So the driveshaft isn't hitting the loop, its hitting the tunnel?

The uppers and lowers are non adj. But I do have a pair of adj uppers I can try on it. You think that might work?

It might help if you could snap a couple of pictures. There's got to be something a miss there. I've never ran into that before, and don't think any of my buddies have either.

It sounds like your pinion is pointing up, and that shouldn't be happening.
