Not a purchase unless you count the mini-grinder wheels that I bought to do the work but did end up having to shave a second set of clam shells for my 85 because the first set did not fit. Apparently GM did not make one clam fits all but took the basic construct and altered it to fit the application, i.e. G, B, and F bodies and G/C/K vans/trucks. No idea what the first set came from. I do plan to post a full set of comparison pics over in the project zone.
