Best way to convert lug pattern

[Crabass]

Hi guys,need some guidance as my searches are turning up zip. I have an '87 R10 fleetside shortbed that I want to start cleaning up, wheels and tires being one of the higher priorities. I'd really like to use a set of third gen Corvette 15x8 slotted aluminum wheels that I have, but that requires converting from 5 on 5 to 5 on 4-3/4 lug pattern. I'm wondering if there has been figured out an efficient "parts swap" (rotors, axles/drums) method of accomplishing this on these trucks, rather than resorting to adapters. Thanks.
