I searched and could not find a definitive answer to this. I have a 99 4x2 Tahoe that I plan on swapping a 14 bolt 9.5" SF under. I also want to use late model 18"GM wheels. From what I've found 5 lugs have 4.5" backspacing, but late model wheels are roughly 6" BS.
If my math is correct, I will need a 4x4 rear axle to get the correct 68" wms to wms to run late model GM rims with a 6" backspacing, and a set of 1.5" front wheel spacers(which should also take care of any interference issues from the outboard bearing and bearing cap from 88-98 4x2 rotors). Has anybody done this swap before and used stock GM 6 lug rims? I'm not looking to do a big drop on it, just 2" spindles in front and probably 4" drop springs in the rear.
