you have a lot of fab skilz, why buy when you can make for a lot less $$$?
no need for any heim joint unless you want an adjustable pinion angle
no need for any type of rubber mount on the axle either
solid welded/bolted to the axle with the front shackle is all you need
ideal length for the torque arm is as long as the drive shaft to have the same pivot point
truk is on stock springs still, axle wrap would run the driveshaft into a frame x-member
my trans am rearend housing had a boss for the factory torque arm to bolt to
i used a trailer shackle up front for the front mount
if you google 'torque arm design' most attach rigidly to the rear end
