    All this talk I said about tires of 35" or less, you don't need a 14 bolt FF. Well... I'm going to run 35's or 36's and I picked up a 14 FF for $150 today. /forums/images/graemlins/smirk.gif It's out of a 76 3/4 ton Suburban and is open...the only thing I'm not sure of is the gear ratio. He said 4.10, which is perfect, but I see a couple numbers on the ring gear that make me wonder. Here's what it says on the ring gear...
    1 GM 3977334 10 41 9 73

    What does all this mean???? /forums/images/graemlins/thinking.gif

    Ring gear is in perfect shape, wasn't leaking at the hubs, looks great!! I'm too excited, I'm going to convert it to 6 lug in a bit, unless I find 8 lug conversion parts. Anyone selling any? Thanks guys! /forums/images/graemlins/grin.gif

    im not sure about all the numbers...but the 10 is how many teeth on the pinion gear, and 41 on the ring gear, 41 divided by 10=4.10s....

    Good deal, only thing I would recommend is shaving the diff before you put it on, it hangs down a lot, might as well do it now. I didn't do mine, didn't think i needed to, but you know how that story goes /forums/images/graemlins/thumb.gif

    I keep opening the garage door and looking at it...I'm still in shock that I have one.
    No kidding on the impulse buy...read the ad, bought it one hour later after I looked at it.
    I hear you on the shaving it, easy to do while it's out. I know I'd wish I had done it the first time I hang the diff up on a rut or rock.
    It's just too perfect...shock mounts staggered correctly, same ratio I have in it now, open diff waiting for a Detroit...man, I can't wait.
    I need to machine down the hubs and axle flange, buy the adapters, U-bolts, parking brake cables, weld on new yoke to driveshaft for new size joint and I'm ready to roll. /forums/images/graemlins/thumb.gif
    One question, the larger tubes of this axle, how much will it pick up the back of the truck?

    Going 6 lug to keep it simple. Otherwise I'd need 8 lug conversion parts and new wheels. I could just get the 8 lug conversion parts and then get 15x10 8 lug wheels, but I'm trying to compare cost of doing either one right now.

    just go to a few junk yards every week or so, and look for the outer parts for a 73-87 3/4t pickup or suburban. That's all you need (hubs and all that stuff)

    *start Hijack*

    Why dont stock wheels fit the 6-lug converted 14ff? This is the first time I have heard that

    *End Hijack*

    The center hole for the axle flange is too small, it's smaller than aftermarket wheels.
