Pantera,

-------While all the frames are "basicly" the same every year of the midyears 63/67 are somewhat different. The only difference in the correct sidepipe side-rail is the slotted hole that allowed a carriage bolt to sit inside the hole and hang down to accept all the rubber cushions, washers and nuts. Pre- sidepipe frames have no hole in that position for the sidepipe to attach to. Its easy enough to drill a hole and run a lag style bolt up as many do, but not correct. A little more difficult to duplicate the correct hole and slot in the correct location but not impossible.
-------Your early 65 will have another change you may not be aware of. The front crossmember does not have the clearanced area that came along later in the fall for big-block harmonic balancer and pulley clearance. I learned that one the hard way!..........Bill S

-------And you are correct on your 65 NO.11 in regard to the brakes. Years ago I had a long, close look at NO.5, originally a black/saddle leather fuelie roadster. It was also delivered with disc-brakes, and was pulled by engineering and sent to the tech center to become the very first 427 Corvette. How was that car of yours delivered?
