    so what are the specs for a 14bff as far as wheels go?? its an 8X6.50 in bolt pattern i think. but what size center hole for the front hub of my 10bolt?? would 5.15" be the one?? smaller/larger?? and what is the backspacing necessary?? hell, here are the wheels im looking at: http://store.summitracing.com/partdetail.asp?autofilter=1&part=CRR2D3425880&N=4294923107+4294923106+400292+1003+115&autoview=sku

    will they work on a 14bff and 10 bolt front (converted to 8 lug)?? thanks for your help...

    oh yeah, and what's the O'Reilly's part number for a u-joint to go from a stock '87 k5 drivetrain to a 14bff??? thanks again.

    Only two diff types of 8 lug that i know of, 8x6.5, standard for who knows how long, on 3/4 and 1 tons to current trucks, and then the Stupiduty are metric, 8x170 mil. I don't think there is too much of an option on hubs openins on aftermarket rims. Usually one size fits all type of deal. B/S depends on what size of wheel, and if you want the wheel to stick out or in at all. I have a set of 8s on my truck that are 4" B/S, have a set of 12s on my other truck that are 3.75 B/S. The 8s don't stick out too much, while the 12s stick out a whole lot. Slings some mud......

    Your link does not go anywhere. The wheels are lug centric so it does not matter if the center hole is too large as the lug nuts center the wheel. A center of 5.15 will def fit on a 10 bolt. My Dana 60 hub is about 4" in diameter and a 10 bolt hub looks tiny compared to a 60.

    hmm.. that all makes sense.. so what's the smallest backspacing i can get away with while still keeping the wheel and drum brakes from touching on 15x8 wheels, as to keep it as close to 'stock looking' as possible?? 31" tires, maybe 35's in a couple years.. thanks

    I run a 15X8 with 4.25" backspacing and they do not touch the drum brakes at all:D .

    Here are some pics to show how much stick out I have. These are 37X12.5 MTRs
