My torque is hitting the bottom of my car where it attaches to the 12 bolt. I found these threads on a search.

No one seems to have any solutions? Is there anything I can do? I don't know if I can even move the torque arm over and use those other mounting holes.

i would say move it to the other set of holes if at all possible. Also, check to make sure the rear end is centered in the car. if its lowered (or on stock springs, and sagging) and has a stock or non-adjustable panhard bar, your rear end is pushed to the driver's side and contributing to this problem.

I have an adjustable panhard bar. The rear end is centered for sure. I could have swore there was a "lip" preventing me from moving it over and using the other mounting holes. I'll check again.

Is this only with sphon torque arms? Is it a tunnel mounted one, or tranny mounted? Sort of making me worried about purchasing an UMI one in the fall.

This is very common and happens to all aftermarket torque arm conversions whent he car is lowered. The new thicker torque arm to differential mount plate will hit the trans tunnel in the rear.

Just let it do it....consider it sheet metal work required for clearancing issues. It will hammer the sheet metal away in exactly the spot needed so you do not need to use a BFH. Again, VERY COMMON ISSUE

see it all the time. My UMI arm only rubs the side of the tunnel in that spot, but the moser 9" hammered a hole in the sheetmetal behind the rear seat just to the side of the tunnel

For the 12 bolt you need to use that second set of holes but you might even need to do what I did for my moser ford 9". I had to make another bracket cause the damage would have been to much, plus I was able to make the torque arm more straighter into the mount.

Some pic's





In this one the bolt holes are lined up, as you can see how much I moved it over.


same with this one


Ill get some pic's of it installed in the car if ya need, just was waiting to finish up other things and get the car out of the garage first.

Thanks for all the replies guys. I'll start with using the other mounting holes and see if that helps at all.

i don't think you can move the mounting holes. Look at the first picture you posted, on the rearmost mounting bolt, if you look right and down, you'll see there is some casting there that will prevent it from moutning more to the pass. side.

I have my Spohn arm mounted with the other set of holes and it still hits. It will "clearance" your tunnel for you.

I haven't got under the car yet. But here is SPOHN's reply. The same thing as everyone else said. I figure I'd post it for anyone in the future that does a search on the topic.
