I bought the B&M swap kit to put a 350 in place of the 700r4, and now it says that I need an outer torque arm bracket from GM. They even gave the GM part #(10034259). I really don't want to buy this part from GM because i know that it'll be way over priced. Now if i knew what car GM put this outer torque arm bracket on, if any, i could get it at a junk yard. Anybody who has done this swap please help. Kyle

 

I've done the swap twice and never had to buy
anything seporate from GM.The outter bracket the instructions call for is the same one that was stock on the car w/700r4.It's the one thats notched on both sides at the top.
It attaches to the B&M bracket bolted to the trans and you put a small bolt through it and the B&M bracket sandwhiching the end of the torq arm between them.
