    i need soemone to convert 3 and 13/16\" into mm

    i dont have my thinking cap on right now, but i need to convert 3 and 13/16" into mm
    i know 25.4mm per inch, but..

    hopefully its SUPER close to 100mm
    that is the wheel stud bolt pattern of the 87 grand am(FWD)
    5 on 100mm pattern, i have to find a set of four wheels and tires with this pattern, GM FWD had a couple different patterns and 5 on 100mm was the smaller of the two in the 80s and early 90s, some of the chrysler cars had this pattern also

    thanks

    Hummm...lets see...

    3" = 76.2mm and 13/16" = .8125" = 20.637mm
    Sooo... 76.2 + 20.637 = 96.837mm /forums/images/graemlins/grin.gif

    duh for me, in hindsight i shoulda just taken 100 devided by 25.4, lol, my bad...

    i think thats close enough for wheel bolt pattenr measurement, enough to show that they match
    now to figureout stud size and threads....
    anyoen happen to know what 87 grans am use for lugnut threads and diameter ? all i know is that they are small and metric and none are on thje car cuz it is sitting on chassis cuz soemoen stole wheels tires and lugnuts, car runs and drives but wont do such a thing with just the hubs..



    thanks
