I have one of Ben's beautiful mufflers on my car, and i just pulled it out along with the transmission, and noticed it is rubbing on the left back side , small spot on the very far left side, rear where the stock heat shield curves down at the back edge.

I was thinking that it has partly to do with Ben's muffler being straight so it gets closer out to the outside on both sides but only rubs on left.

Can i put some spacers at the rear transmission mount to drop the rear abut 1/4"?
If so, what to use? I have the 911 engine mounts for the transmission mounts with stock hardware and bolts and washers.

OR

option 2 try and bend that shield but those welded brackets hold it really tight.

OR

Remove the shield completely and place heat shield material on bottom side of the trunk floor for defection of the heat.

any other thoughts please they would be greatly appreciated.

If you take the muffler bracket off of the trans does it lower it enough to stop the rubbing? If so elongate the holes on the muffler bracket to lower it.

Show a picture of your trans mount assembly on the car.
IIRC, the stackup is different with them than with stock mounts.
It may be easiest/best to lower the trans by adding spacers on the big bolts between the trans and the mounts.



i will take a picture when i get home. I was thinking that too that a washer at the top of the transmission ear would lower it a tad, i may have to get longer bolts, there is only about a quarter inch sticking out the bottom .

on the issue of the bracket if you do that you are letting it sag a bit and then isnt that putting stress on the HE mount ears a bit?
