I am installing a TH350 tranny behind my 350. I am wondering if anyone offers a little bit less expensive torque arm conversion mount than B&M($89 or so). Also, is it difficult to install and do I need a differnt crossmember or anything else special to swap out the trannies? I have the long tail shaft on the TH350. Am swapping out the 700R4.

i havent seen a cheaper kit than the b&m but there might be one out there just very hard to find

Check the classified's on this site. I just bought the B&M torque arm kit from somebody for $50. I saw another posted yesterday for only $25. Hurry up and contact them and have him send it or hold it for you. The guy I bought mine from said he had to grind the hole bigger in the crossmember so the mount will fit. I haven't started yet but plan on doing this next weekend. The mount will sit about 2" off than the 700r4 mount did. Hope it goes well for you..
