Don't know if this has been posted before but I did a search and didn't find anything. Sorry if it's a repeat. Just bought the parts for a 6-lug to 8-lug conversion and thought I would share the info I found for the cheapest places to get parts. Hub/Rotor Assembly From: RockAuto.com Brand: Raybestos Red Line Part Number: 56287R Price: $41.89 plus shipping ($9.95 for two) 3/4 Ton Backing Plates From: GMPartsDirect.com Brand: AC Delco Part Numbers: 14023421 & 14023422 Price: $62.15 plus shipping ($27.34 for both) Everything else swaps over from 1/2 ton (all 10-bolts, late model D44s). Brakes, spindles, knuckles, etc. Rock Auto also has spindle needle bearing kits (bearing and oil seals) for only $8.70 plus shipping each. That's $5 less than NAPA, including shipping charges. I got the rest of the new seals and bearings from my local parts place but if you're really cheap, all the 1/2 ton stuff swaps over for those, too.
