I'm restoring a 52 Chevy, and the guy at the body shop tells me it would be cheaper if I bought new reproduced side bed panels rather than him working on the old ones. The original panels do have some dents & need some work, but they're not rusted (I've already purchased a new front panel & tailgate - they were in pretty tough shape). The new side panels are 16 gauge. Does anyone know the metal gauge of the originals? Are there other issues I should consider? Thanks for your help/thoughts. Bob
