I do and had a problem surface. I bought a 75.00 fording stack and bolted it on. It did not meet my exhaust correctly. Since I was not ready for a new rear exhaust section (good luck finding NOS) I left it alone to be addressed later.
The road vibration eventually tore all the expanded steel at the welds on the upper mount. I had a friend who had a welder small enough to do expanded steel fix it. We had to sleeve the expanded steel and weld the upper mount to the sleeve. This is a very lame design (stock) and the mounts should have been attached to the exhaust pipe not the expanded steel. Since I already bought another one from the same place (now 150.00!!) I have made a small bracket to hold the bottom to the exhaust mount next to the tailpipe. I highly recommend doing this to provide a third anchor point if you are not hooked up to your exhaust pipe.

Just a word of warning since this stuff is not getting any cheaper.

Oop's this was supposed to be another thread. I can't find my car keys either...
