Since you allready have it,the 1/2 ton 86 truck rear will work out just fine for a stocker or mild custom. Its an inch wider, no problem.I have a 80 rear in my 51, with 7 inch wide rims and 235 tires ,the tires are within the fenders. Use the stock springs and buy weld on spring saddles and U bolts from your local hot rod shop.On my 51 I reused the stock bolt on lower shock mounts.S-10 lower spring plates work out fine with some minor bolt hole enlomgating.Some guys say an Astro van driveshaft works for them, or a brand new one can be made for less than $200 Swapping the rear springs is an improvement, but if you are on a low budget, the stock style springs minus a leaf or two rides ok.
