I am restoring my 1958 Apache 3100, shortbed, stepside, 6 cylinder, truck. I am attempting to keep it original. I need a muffler "support assembly" (# 3722793) as shown in the 1955-1959 Truck Factory Assembly Manual (Sect 8- sheet 16). It supports the back end of the round muffler. I need the metal "cradle", that goes over the muffler. I was able to purcase the "strap", that goes under the muffler. No one seems to sell this "cradle" new. Anyone have one (in restorable shape)? Thanks.
