I noticed that the paperwork photo you included says 58-64 FULLSIZE Chevy. You say they verified that they are the correct parts?
here's a thought, have you checked the catalogs of other parts companies? if all of them say that 59-60 are completely different, then yeah, I would say that SWPP is feeding you a line. either they invented a 'universal' part no one else has or they're ignorant. sure wish Keyser was online, he seemed to know all those swap-compatibility partsSo they say...
I always thought 59-60 were all their own... Everything bolted on easy enough with the exception of the shocks.
