I purchased a complete quanta chassis kit for my 68 and the techincal guide page they provide regarding the brake calipers is bulliten#40-67SUB which refers a 67 not a 68. A bottom footnote they printed on the page states NOTE: SUBSTITUTION BULLETIN: At this time we do not have documented examples of the information of your year corvette. My question is, does anyone know what are the correct markings that go on the brake calipers. If you could someone post an example. Thank you Jeff
