    Anyone know where the build data plate is on one of these? not in dash
    Planning to change all fluids
    Allison 295 in the trans (much better than Dex VI) and steering/ power brakes
    DOT 4 for the brakes
    Guess I'm stuck with Orange Dexcool
    add coolers for trans (has a wimpy one) and engine
    I have found that for trans 1/2 inch lines flow much better than 3/8- will add a filter
    IDK about engine yet will uses stacked plate coolers IDK about lines yet
    notice lack of baffles between grille and radiator allowing air to flow out wheelwells and not through the AC and Radiator
    It has new tires- not my choice but OK
    any suggestions appreciated, I will start a thread if appropriate
    tks

    found some lug nuts rounded off- at least I'm not on the road
    are they Metric? 7/8 seems loose

    7/8" is basically 22mm(within a few thousandths of each other). The 2500/3500 lugnuts with the hubcaps and the thread on nuts should be 21mm, 1500's are 22mm.

    I've never used anything other than a 7/8" socket. Maybe a 12 point socket was used on them.

    Same, and everyone in the fleets I worked with. Thousands of tires changed. No issues.

    got out the mic 22mm
    21 will not fit, can't find my 22
    it's about .010 different than 7/8
    I tried a craftsman 6 point 7/8 and it would not get the rounded off one off
    I'll try a good 22 6 point when I find mine or I'm off to Sears tomorrow
    not something to try Harbor Freight on
    good point about the 12 point NVW thanks
    otherwise it's plan B the air chisel
    still glad I'm in the driveway and not half way to nowhere
    I'll try and take all the other ones off first and try and get the rim to move
    sometimes that helps
    thanks guys

    Then I must have gotten them backwards. Could have sworn I used a 21 on mine.

    I pulled the hubcap off the other front- looks ok
    now tomorrow the rears
    Have not found my 22 so go get one tomorrow
    would like to get the rounded one off without total destruction
    holding a new Craftsman 21 in my hand as we speak but too dark to try tonight
    I'll double check tomorrow
    21mm is .8268
    22 .8661
    7/8 .8750
    will advise
    Have not found my 22 so go get one tomorrow if 21 is a no go big difference almost .040

    REPORT
    Bought a new 22mm six point impact socket
    virtually NO wiggle
    7/8 six point has considerable wiggle
    7/8 12 point would strip
    I replaced the stripped nut as it had considerably more slop than the good nuts
