Had 350 TH350 '70 elco. put in 454 TH400. to install trans brace crossmember it had to be located further back using stock holes in frame. everything looks to be fine except the location of P brake cable. not finding a hole to put the cable guide into-the 6" J bolt. I think to get the cros member in right i had to give it a 180. I could drill a new hole... The tuff part is trying figure if the cable should run over or under the trans cross member. any body else been through this? thx J.
