    I have an assortment of different lug nuts on my truck, and I just want to start over & order new ones. The truck is 150 miles away and I want to be sure of the stud size & nut taper, so I thought I'd check here first. I do know one side is RH, and the other is LH threading, but that's about it.

    Really? Left and right on a 70s truck? I didn't reale they still did that by that point. My 1210 has normal thread on both sides.

    I thought the same, as my 1210 with D60 & D44 (8 lugs) are all 1/2"-20 RH thread.

    My '75 One Ton 4x4 truck has the LH thread on the Left side and RH thread on the Right side.

    I thought all 1310’s were duallys. Mine is anyway.

    5/8-18 sound right for threading?

    Thanks for all the replies!

    5/8 - 18 TPI is correct, IIRC.
    One tons with a Dana 70 rear axle has single wheels. (9,000 GVW)
    One tons with RA-15 rear axle has dual wheels. (10,000 GVW)
    The GVW of the truck determines which axle was installed at Springfield.

    Dorman 611-060.1 is pretty much the only one I've found that looks like it fills the bill (gotta check the taper on my tubeless wheels), but what a bill: they're priced as high as $16 each!:saddam:

    Jegs has them for $4.79 ea, but even at that price, I think I'm going to put off this whole idea until I can get a count of how many left-hand lug nuts I have (if any) that match up to the 1 1/16 hex & 29/32 height of that part.

    Makes sense not to replace the good ones. Did you go to rock auto?

    I'm going to have to disagree on the axle use claim. I have 2 FA52 dually trucks, one with RA15 and the other Dana70. The 15 truck is a 74 and 10k. No cab on the other but it's probably 70 to 73.

    Chris, I have a box of rht nuts if you need some.

    You should make sure what tubeless wheels it has as well. I put "coined" rims i found on a mid 80's ford on my 73. They use regular lugnuts. On my 75, it has lugs with flat flanges.. they are still Ford rims though..[the 75 has lefty threads too]

    Rock Auto won't deliver to Colorado, so I don't tend to go there. If they do have the required nuts, I can have them delivered to WY, though. Thanks for the idea.

    Coined, with 45º tapers. I have to revisit the Dorman website, because 60º taper sticks in my mind.

    Just checked out Rock Auto: 5/8-18 LH lug nuts are no longer in stock, checked the manufacturer's website (Powertrain Components) and they are no longer in production. Shame, too, because they cost something like a $1.50/ea.

    Two places I go to for those hard to find parts are:

    Border Parts: http://border-parts.edan.io
    and

    E & M AUTO PARTS
    El Cajon, CA 92021
    6194443118 (Main Phone)

    Border Parts will ship. Not sure about E&M.

    Try AM auto parts. No where near the selection of rock auto, but good prices on closeout parts. Sometimes better than RA.

    Nothing there either.

    I'll call the two salvage yards above tomorrow, but having matched and presentable lug nuts on this truck is looking like more trouble than it's worth, in both time and $$. As hard as it seems to be to locate 5/8-18 LH lug nuts, I consider myself lucky to have any at all.
