    Just doing some planning for the future upgrading of the 10 bolts. Trying to decide on a 14bolt ff or a dana 60 rear axle. Would probably like to run about a 36" tire, but as these things go it might be larger than that. How much weight & ground clearance would be gained by going with the 60? I'm aware that the 60 can be geared lower & has more choices in the locker selection. Now what would the price difference be? I know that 14's are pretty common and one out of a 3/4 ton pickup is a bolt in. Any idea what came from the factory with a 35 spline 60 in the rear.

    Thanks,

    - Jay<P ID="edit"><FONT class="small">Edited by grtwhite on 08/01/01 11:25 AM.</FONT></P>

    14 FFs are way bigger (10.5 vs 9.75) and are a straight bolt in. Put a 14 bolt in it.

    Dana 60s come in some Dodge and all 3/4 and 1 ton Fords.

    Most stock D60 rears come with either the 16 or 30 spline shafts. The 35 splines are more rarer and were more available in the newer Dodges. Fords still used the D60 but most of the rears were switched to the Sterling 10.25" during the '80s.

    Thanks for the replys. So are you guys saying, just go with the 14 bolt due to less hassle &amp; expense?

    The D60 would have to be modified to fit in a 73 and up truck I believe. If you are gonna go that route then just go for the 14B FF. Otherwise look into a 14SF or a beefed up 12B.
