The round bushing has a bolt through the center which holds the three hole bracket. The other one just squeezes around the front of the TA. Brian

Mounting the torque arm was not simple. Unlike every other H-body, the 2.5l 4-cylinder models use a "lipped" torque arm bushing instead of a round one. This is the same as is used on 1982-current Camaros. It's a little better because this arrangement allows the torque arm to slightly move in and out of the bushing, which may help prevent wheel hop. So, I had to find a way to mount this "oddball" torque arm up to the TH350 transmission I was putting in the car. Plus, the torque arm was now 3.5" too long since the V8 drivetrain sits farther back than the 4-cylinder one.
I could have just used factory parts from a V8 Monza, including the torque arm (round bushing) and TH350 tail housing. But I didn't know where to find those parts at the time (this was before I joined HBOA). I found a B&M kit for putting the TH350 and TH400 into 3rd- and 4th-gen Camaros in a racing catalog. This kit comes with a bracket that attaches between the TH350 body and tailhousing to which the torque arm mounts. Then I bought the "clamshell"-type bushings from a Chevy dealer; ones for a Camaro work on the Monza torque arm. (Beware: although all 1982-up Camaro torque arms are the "lipped" type, the "lips" face different directions depending on the year and drivetrain, so be careful if you go this route!) The specific part numbers I used were: GM 10024028 insulator + supp and GM 00527689 insulator.
