Which Torque Arm are you looking at, the frame mounted or tranny mounted? The frame mounted one from BMR may not work with your Y pipe and/ or longtubes.

i think its tranny mounted? didnt kno there was a specific difference...will that work out with it all QTP or Kooks (catted Y) GMMG if thats what you wanted to know was the setup and Torq arm....will that work with a Moser 12 bolt?....is there anything specifically different about the 10 and 12 bolt suspension suspension mounts or antyhign...will all BMR suspension work out with it?....if it were really necessary would even the stock suspension match up to it?

The tranny mounted Torque Arm will work with longtube headers. So will some chassis mounted Torque Arms, but the BMR Chassis Mount can have problems.

As far as the 12 bolt, just get one from moser or strange that has the F-body suspension setup. Most people prefer the Strange because it has a better torque arm mount, but it's a little more expensive. Search some threads for more info.

The 12 bolt should bolt to all stock suspension pieces except for the Sway Bar. Most aftermarket suspension manufacturers sell a kit that should be welded to the axle tubes and then u bolt the bushing to it.

Just my .02

Moser and Strange both have specific designs for your F-body. You need to know if you have ABS and or Traction control, year, gear ratio, and differential type.

Here's a link to the picture of the sway bar bracket.

But have the bracket welded on.

Not helping with your question but giving you some advice. I have QTP's, ORY, and GMMG. Great headers and the system sounds awesome, but do yourself a favor and go WITH cats. The exhaust will have no rasp and sound really really nice. I had to have a 12" bullet welded in, and there is still so rasp. QTP's are awesome and the GMMG is great, just go with some cats.
