Think it was Cleanaway in Sydney tried a few of these out, had the 673 Mack engine and either a 9 or 10speed Mack box, small 34000 lb worm drives on the lightweight camel back suspension. Wouldn't swear to it, but believe you could option the Allison slosh box as well.
But as usual, IDSTBC. (All care-no responsibility)
The cabover truck MIR model with set forward cab used the cab from Brockway N527TL Huskiteer. It came into production range after purchasing the Brockway company by Mack Trucks. The MIR model was equipped with a diesel engine MaxiDyne with output of 237 hp and 12-speed gearbox with two levers.
Lang, That is a sharp truck.. Mack bought Brockway in 1956, BUT did not combine the design engineering departments until about 1974 for the introduction of the R model cabs on Brockways in 1976. I do not remember Mack using this cab in the States?? I Think Mack's LCF cab for city tractors and refuse trucks was different??Mack used Brockway's new tilt hood design to be introduced in 1978 for the American long nosed Superliner.
