Torque Arm for 55 chevy

[Marshchevelle]

I'm building a no frills pro-touring /Autocross 55 Chevy 2dr post car I'm hearing from the circle track people around me that a torque arm suspension would be the best set up for low cost and simplicity.I'm hoping someone has done one or something slimmer I have a 8.8 ford rear In it now I'm planing on using I'm just not sure if I should use a f-body kit or something for the 8.8 Rear
Thanks Any advice is much appreciated
