    Yeah i once had a DM dump with a 285 that would turn 2300 RPM'S, with the 1070 12 spd, and 4.17 rears, it would bury the 80 MPH speedometer. terry

    Some of the early mack wheel bearings had a inner seal to separate inner and outer bearings, the inner was packed with grease and the outer run in gear oil. most guys just knocked out the inner seal and run oil in both bearings. terry

    Can,t say for sure, but the older 12 spd had a regulator that cut the trans working pressure down to about 60 or 65 pounds. terry

    The RL is a straight frame, where the R model spreads out around the engine. right? terry
  22. terry
    I would bet a R model mount is different from a RL mount. terry
