Looks like your going to be needing some torque arm bushings as well!

I am struggling big time finding part numbers 

[Geoff Weeks]

Atro should be able to either get bushing or possibly whole torque arms :

P.S.their older catalog, had the bushing by dimension as well, their newer catalogs I find harder to use.

I might have an old Atro cat on a hard drive, if I can find it I'll post it.

What you have at the rear is a common style Mack chassis crossmember. They were used on many trucks with Camelbacks and other rears in the central portion of the chassis. Just were put upside down overthere. More correctly, the very rear crossmember on your truck put upside down to clear up the trailer pin for coupling (and that's a common practice). Those "common" crossmembers may have holes for the shock brackets. If no you just drill them. There's one point though you need to keep in mind. Frame width is different between RW and earlier Mack model such as R, U, DM, F etc (which used to use those members) Those are narrower so you need a parts from a RW2 (after 1985) or MH Ultraliner (similar chassis). Or you can use a R-model part adding spicer plates.

P.S. CH and later models have different distance between the rails too.
