    Hey guys. As some of you know, I am slowly planning out the conversion of my truck's IFS and 10 bolt suspension into a 1 ton solid axle suspension. Well, the front was easy, a Dana 60 of course. Now, on the rear I have a few questions. I want to put a Corporate 14 bolt FF there, because of the beef and cheapness of them. However, I would really, really like to stay with 6 lug axles. Now, I know they never made any FF with the 6 lug style, but I've often heard that someone saw it at a truck show, or has heard of it, etc. Okay, does anyone actually know how to do this? Or know where to look into it? Any help would be greatly appreciated.
    Next option if I can't find that is to just put a Dana 60 in the rear. I'd rather the Corporate for the reasons I said above, but if I have to, the Dana 60 should do. I am only planning on running 35x12.5's, maybe 36's or 35x15's. Would I have any problems with running a well built (Dynatrac or the equivilent) 60 in the rear? Above all, I want to know that unless I do something completely stupid and unsafe, the rear will never be a concern.
    Any help is greatly appreciated guys.

    The hub on a FF 14 bolt is too big for a 6 on 5 1/2 wheel pattern. In your position, I would look for a 6 lug 14 bolt semi-floater. Stock bolt in axle, and plenty strong enough for 35s. No problem to run 15" wheels either.

    Would you be interested in writing an article for www.off-road.com when you do your solid axle conversion? Let me know if you're interested. The article would be $100-$200 depending on the detail.

    Dynatrac will sell you a custom front axle for the 6-lug wheels. There are no OEM 6 lug dana 60 hubs that I know of. For the rear, you'd prolly be best off with a 9.5", semi-floating 14-bolt from a newer light-duty 3/4 ton (also found in 1/2 ton diesels, 88+). Otherwise you will have some more of that super-custom stuff from dynatrac for buku $$$$. They make great stuff, but $$$$$.

    OR swap in GM D60 front and a D60 FF rear from a ford/dodge. The D60 is lighter and a bit smaller than a 14bolt FF.

    That is the first time I have seen a 6-lug 10.5" 14 bolt...but it looks like they converted it to a semi-floating design.
    In my opinion the semi-floating 9.5" 14 bolt would hold up fine with 35's and should be fairly close in strength to a Dana 60.

    Shawn, I'd be more than interested, I'd be honored and thrilled. Heck, my mom would be thrilled out of her mind! (She's an English teacher) Got a problem though. I'm a 21 year old US Marine who doesn't make much money. That, and the little things I have to fix, along with my girlfriend living in New Zealand and I may have to move to NZ to be with her (I hate the INS!)after I get out, and sundrey other things are making it difficult. So it will be a while before I have the money to do any of this, and I may be leaving the country for a while in a year and a quarter. So when I do it, I'd be honored to do it. Unfortunately when that time will be isn't fixed yet. Right now I'm just planning it all out so that I can just start ordering parts and peices as soon as I have the cash. My email address is ajm_blazer@yahoo.com if you want to communicate more directly. Thanks for the offer anyways.

    Thanks a lot 84! That is exactly what I was looking for. I am going to pass that on to everyone on the other BBS's I post on. I've already sent them a message with a bunch of questions. Thanks again man.

    Well guys, turns out that it's a FF that has been converted to a SF, and costs 2G with exchange. UGH! I don't have one to exchange either. Considering that for the same cost, I can probably pick up a good 8 lug 14 FF with 4.11's, a 8 lug Dana 60 with 4.11's, and four 8 lug 16x8's for the same price, I guess I will just go that route. I can probably even get a good locker or limited slip too. Oh well. Thanks anyways.
