    What trucks have 14B axels on them? And what gears do they come with in them?

    Many. Memorize the size and shape of the diff and then start yanking covers 'til you find the gears you need.
    You will probably want to avoid a Gov-Loc if you plan on a locker. That is another reason to pull the cover.

    I think the only 14FF to avoid is from vans.
    Get more advice on that tho.

    14 bolt FF came from the factory with 3.73, 4.09/4.10.4.11(seen em all, don't know if they're really different) and 4.56 gears. There is a carrier break betw. 4.11 and 4.56.

    Beware the extra-sucky Gov Loc.

    Van axles are about 3" wider than trucks, so you can use them to widen the rear track closer to the front. You'll just have to weld on new perches.

    Stay away from Dually rears, they are narrower.
    1 ton trucks w/single wheels are the right width but the perches are different center so you'll have to re-weld.

    3/4 ton trucks are same width and same perch centers. Direct bolt in. Make sure it's the FF in 3/4 tons after about 83 or so.

    Lift It, Lock It, LIVE IT!!!

    Also the spring perch changed from cast steel to stamped steel in 85 or so. If you get one from a 1 ton the stamped are easier to cut off and reweld. Also I believe 3:42 gears were available too.

    Get ahold of Brian60s - he probably has two brand new 14Bolt FF with 4.56's still in the box. I orderded mine and will be receiving it soon! Send him a PM or look on the for sale forum - his post is usually near the top.

    There are also 2 different sized brake drums, one's 13.5" and the other's 11.5" if I'm not mistaken. No idea which one stops better and 15" rims will fit over either one. I've got the big drums on mine.

    I have been looking at 4.56's fronts. You looking for just the rear 14B FF? I have found one here on ck5 and a friend of a friend I guess has one that I might check out, but here is some places i would look to that have a good selection of parts...

    Twin City Auto Salvage (651) 774-3339 (might not work anymore) or try 1-800-532-7487. They may of cnahged their number cause I did try them a few days back and it was messed up... if not look them up in the St. Paul phone book. They deal in lots of auto parts and military supplies.

    French Lake (320) 274-8497
    Viking Auto Salvage (651) 460-6166

    I have also had excellent luck from Ruff and metro auto salvage... not necasarrily these trucks though... I don't have their numbers off hand.

    I am looking for front and back 4.56. But if I can only get the rear for now that is fine with me I guess because I just don't want to fry my tranny. I will just keep it out of 4wd until I get the front too. So the back is most important to me now.

    Thanks for the help everybody, I will check those out numbers out.

    So how would you identify the gov-loc? What are you looking for/avoid? THANKS!

    If it doesn't sit on a frame, then it isn't a truck.

    You need to pop the cover off to make certain - a worn out one will feel like an open diff.

    Once you have the cover off, try your best to see the spider gears. An open diff has a few small "windows" where you can see teeth. The Gov-lock does not have these windows - only some small cutouts where you can see clutch pack material.
