Sorry man, you got the same ones as me than, just got a set off a 70 cuda, seem to match mine, the first guy said 71/74 so I just thought it was 2 sets, I'm not positive what they belong to, maybe a 71 cuda, with the duals or a challenger, I still need one more set for the other car, or I will hack up the ones I bought & attempt to reweld the joint & weld one of the mounts on each? never welded stainless, don't know what to expect? Rich
the big ones are about 7" dia. the smalls are bout 5 3/4"
