    After reading just about every post in the last six months on this topic, I'm still wondering what to do. My truck came with some Alcoa 15 x 10, 6 lug rims which I'd like to keep. So, I see my options as:
    1) 14bff, turn hubs, use adapters
    2) 14bsf with 6 lugs. These were made between 198x? and 199x? and were on 1500's, 2500's and Suburbans. Yes? No? Does spring perch width get wider in later years?

    Which is the best option for price? Can I get from here to there for say $300? $500?

    Option number 4, ditch the bling and go 8 lug like the rest of us. /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    Yeah, going with 8-bolt rims is something I was thinking about. Then I've got to upgrade the front axle, which seems to me to be yet another can of worms. I was just trying to keep it simple.

    Simple, 4 15x10 white spoke rims, powdercoated, $40 each from 4WPW or Summit or one of the mail orders from a 4wd magazine.

    It's cheaper than adapters, new axleshafts, or anything like that.

    You'll need a 4 1/2" grinder and some discs, but you needed that anyway. /forums/images/graemlins/thumb.gif

    Understood about the rims, that's the no-brainer. Upgrading my front axle means that I either have to find a D44/D60 or update my front 10 bolt to 8 lug - something I wanted to avoid - mostly because finding an axle means that I'd have to go through it, which is fine, but that's just another to-do. Again, keeping it simple and lowest cost is my goal.

    Swapping the front 10-bolt over to 8-lug is pretty simple and cheap. If you can repack the bearings than you can do the swap. I bought complete hub assemblies from the junkyard for $50 and bolted them on in about 2 hours.

    Thanks for that! That's good to know. So, figure $250 for the 14Bff or so, $50 for the 10bolt conversion, $200 or so for the rims and we're at about $500 give or take.

    Yep just make sure that you have matching gears front and rear. If you get a 14BFF from a junk yard take the front axle too /forums/images/graemlins/thumb.gif Maybe you'll get lucky and score a D60
