Rear cross member

???Do you mean rear bumper? ???

 

crossmember, rear bumper it's the same thing.

and yes your plan should work.

 

i was thinking about this and came up with this.
it's a crossmember. it's part of the frame. and has bodymounts on it.
the 40's don't have a rear bumper, they have/had those two bumperettes.

but whatever, i don't get paid enough to think.....

 

My fault. When I think of crossmember, I always think of that tube behind the tranny.

But yer right it is a crossmember.
