I have a A code 67 fastback shell, I bought a while ago, that I just got on a rack. I am curious about this bracket to see if this is the dual exhaust brackets that I have heard about. It is bolted to the frame rail just behind the axle snubbers. If so, were these normal on all A codes in 67? Does it mean anything more like it was a GT or anything? I haven't got to the point to order a full Marti report yet. Just thought some of you guys could help me out. The bullit proportioning valve is still in the rear of the car also. Thanks for any replies.
