    I can tell you my SemiFloater is 31/2". Does that help?

    The axle tube diameter is 3 3/8" for the 14 bolt FF.

    Hopefully this helps. BDS lists for a 77-87 3/4 ton 4x4 (which houses a 14FF rear) rear ubolts....P/N 040032, Diameter is 5/8", Width is 3 5/8", length is 10", and they are the round style.

    I second what Rene said. 3 3/8" is the diameter of the tubes.

    I will bet you a million dollars that it IS that measurement. [​IMG]

    I called the dealer and told em what I had. 1979 K20 pickup Corp 14. They told me it was 3 1/2. Does the year make a difference?

    I'll add another measurement of 3-3/8" to that tally....that's what I measured off my 14BFF.

    I cut a 3-3/8" hole template for new spring pad mounts and it fits perfectly. Not too tight, and not too loose.

    Why do I have this feeling that the parts boy at the dealer was smoking something funky?

    Ok, I did what I should have done the first time. I took a pair of "C" jaw vise grips and tightened them down till they would drag just a little back and forth across the tube, then measured the opening. 3 3/8" exactly. When I "eye-balled" it earlier, it looked like just under 3.5 but just over 3.375. Obviously it was an "optical conclusion [​IMG]

    Because he was and he does not give a crap what the actual true diameter is. He just wants you to leave him alone so he can concentrate on getting his BUZZ!!! [​IMG]

    Of course, that's what I said... You should read more carefully... {rolling eyes up to ceiling and whistling casually}

    And why does Leadfoot say
    "Diameter is 5/8", Width is 3 5/8", length is 10"

    3 5/8?!?!?!

    Argh!! Cornfused!!!

    And WHERE do you get some size like that?!? I went all over, NAPA, CarQuest, AutoZone, etc and NO ONE has 5/8, 3 3,8 or 3 5/8 and 10 long!!! Where do you people get these at? I don't want to buy them from the dealer for $20 EACH!!

    Go to Farm and Fleet, thats where I got mine. The 5/8" is the diameter, the width between the 2 legs should be 3 3/8" and the length should be about 10".

    Where are you measuring "between" the legs? From the middle of the post to the middle of the other post? Or from inside of the post to inside of the other post? Or from outside to outside?

    I did not see at F&amp;F anything labeled 5/8 3 3/8 and 10". I found a 9/16 one that was close....but not the 5/8 that this axle is gonna need!!

    Thanks

    I never measured my axle, but I am looking to replace the lift blocks with lift springs and needed to order new u-bolts. I looked at the BDS website click here

    I measured from inside to inside.
    I got mine at the F&amp;F here in Urbana when I did my swap. I dont think mine were that long though. I did the shackle flip on the rear so I just measured from the inside of the rounded end to the tip of the legs. (I want to say about 6 inches but Im not positive on that. )

    I can look at my reciepts, it might list the part # or something.

    Another thing, If you look at the back of the package they have a list of all the sizes or how to order what you want.
