I'm in the process of building my 87 Z/28. I have a new 355 ready to go in, and i got a good deal on a rebuilt TH350 transmission.
My question is about the mount for the torque arm onto the tail-housing of the 700R-4. What are my options for re-mounting this onto my TH350?I was thinking of fabricating a new bracket onto the four housing bolts on the rear of the transmission. Is there an easier way? Im prepaired to either lengthen the old torque arm, or build an adjustable one from scratch.I'm looking for the easiest (but not "Mickey Mouse")solution. I'm not ready to go to a four link orladder-bar setup.

 

There is a torque arm relocation bracket that moves the mounting from the end of the extension housing onto the trans xmember. I can't remember the site but someone asked a similar question recentlyin regards to using a TH400. Try doing a search for torque arm relocation bracket or check out Jegs or Summit.

 

Yeah summit has the change over kit by B&M (part # BMM-30299) and by Hurst (HUU-5500001).
