    I havn't seen it yet but what did the 90 Furds come with? He didn't know for sure if it was from single or dual wheel but he said for sure 1 ton.

    it's either a ford sterling 10.5" (equivilant to our 14bff) or a D70. i think. /forums/images/graemlins/crazy.gif

    the D70 looks like an oversized D60, while the sterling has a really wide diff case. i'll try to find some pics for ya.

    that would be great thanks. I am wanting to make a Dually Suburban, would the D70 be a good canidate? Are all 8 lug bolt patterns the same?

    Not sure, but i think that is only partially correct. IIRC one will fit on the other but not visa versus. (ex: chevy rims will fit ford pattern, but ford will not fit chevy.....just example here)but IIRC the center hub hole on the rim is a different size.

    any particular reason you would choose the 14b over the d70? it looks like I can pick this up for $75.

    The rear D60's and D70's seem to be harder to find spare axle shafts than the 14FF where as the 14FF is a plentiful item /forums/images/graemlins/thumb.gif

    D70s and 14bffs are about the same strength really. i've only heard of someone breakin a D70 shaft once and never heard of anyone breaking a 14bff shaft. oh and ford rims fit on chevys, i used to have 2 ford rims on the sub when it was all stock.

    it's the chevy center holes that are smaller so ford and dodge fit chevy but not vise versa.

    Newer Fords have an 8x170mm(?) METRIC bolt pattern.

    I am selling my 14 bolt for a Dana 70 so I can use an ARB in the rear. Dana 70HD's have 35 spline axle shafts which are theoretically stronger but both will work good in a dually sub.

    [/ QUOTE ] I'm gonna say that it is the other way around. The 14ff has a third bearing to support the pinion gear where as the 70 does not. Ring gears are almost identical in size (d70 is something like .04'' bigger) and axle shafts are about the same (but like said before, i've seen broken 70 shafts but never a broken 14 ff shaft.) Another upside to the 14ff is that a detroit locker can be had for about $300, but a down side is that you can only gear as deep as 5.13 I believe the d70 has gearing into the 7's!
