I have read a number of posts about a dual exhaust bracket hanger being welded to the frame to help identify an SS. What does this thing look like? Is it a thin piece of metal or is it pretty stout? My 68 SS has 2 pieces welded in about the right location, but they are probably 3/8" thick steel and it looks pretty much "not factory". They look pretty rough, like they were cut with a torch. Would someone have welded these in to stiffen the frame where it makes its bend around the axle?

68's don't have them at all..it's only on 69's..for 68 they used compression nut.
