I'm sure this has been a thread before but could not locate it anywhere. Does anyone make a bracket that allows you to bolt the factory torque arm to a GM 12 bolt? I have a 12 bolt out of a Chevelle that is the same track width as my factory 10 bolt (from an 86 Camaro). I was planning on cutting off the coils spring, control arm and pan hard brackets and then welding them on the 12 bolt I have. The problem I see with this is the torque arm. I know Currie make a bracket for a Ford 9" to *82-92 F body but haven't seen anything for a 12 bolt. Any help would be greatly appreciated. Thanks, Mike
Forgot to mention this is going into a 91 Trans Am; in case it makes a difference.

 

Not without a lot of fabrication work. The cast housing of the 12 bolt isn't good to weld some sort of mount onto. You really need to heat up cast with a torch before welding to it and then you risk distorting the casting for the bearings. A "bolt on" mount bracket isn't really strong enough for the stresses placed on it. If you don't think you're going to stress it that much then a 10 bolt will be fine but chances are you want to install a 12 bolt because you're going to abuse the 10 bolt.

If you want a 12 bolt, you'll need to buy a direct bolt in one from places like Strange. Trying to adapt a 12 bolt from some other vehicle wont be easy.

The Currie bracket for a 9" is easy because the mounts are easily welded to the steel housing. The 12 bolts cast housing makes that very difficult to do to be safe.

 

IT WAS EASY TO PUT AN OLDER GM 12 BOLT IN A THIRD GEN,, I WILL HAVE PICS SOON...............

 

We just had a thread last week, though it may have been in the sub-forum for fabrication. Detroit Speed makes a 12-bolt torque arm setup for '67-'69 camaros, you may be able to adapt that. I expect it is strong enough for whatever a stock 12-bolt housing can survive.

 

Do you have a link to that or the thread? Thanks, Mike
