Guys, I have a 408 LS motor with a turbo 400 in my 1991 bird.

Has anyone seen a double hump cross member that will work for a turbo 400? I need some space for my exhaust system (stainless works lsx swap headers)

I simply cannot find a good way to route the y-pipe past the Spohn transmission cross member.

If not would a double hump for a 4l60/700r4 be close enough to modify? (of course using a BMR trak pack torque arm )

Thanks in advance!!

J. May
