I have a mid 1959 Corvette and had some trouble finding all the correct exhaust parts. After some digging it is clear that at some point the rear body ducting was replaced with a FG exhaust duct or housing assy 3762441/3762442 ( used with 3762440 extension) As noted in the AIM the 2 - 3762440 extensions replaced 2 - 3740295 extensions like my car has ( the right rear bumper had welded bolts and had to be removed so the extension could be removed from the rear.. I can find no data on the mufflers listed in the AIM, it is appearant the the front extensions were welded to the muffler ( #3752553 and 375255?) at the factory and any replacement mufflers were bolted. Most of these replacement mufflers are 3752561/62 and have noticable differences and are designed to be bolted. There are lots of NOS off road mufflers floating around but I not been able to locate any NOS stock or oval mufflers that are even close. thanks and comments welcome
