The 8V92 is from the AMT aerodyne kit. I got the torsion bar suspension from P&P resin works and the spoke wheels are from a diamond reo kit.
My family ran a trucking business for about 50 years before selling it a few years back. Through the 60's and early 70's they primarily ran K123's with cummins engines, then switched over to 8V92's in the mid to late 70's. In 1978 they bought a few matching green and white K123's with 8V92's. For this model I am trying to replicate one of these as best I can.
These still had the skinny grille (they went to the wider grille a year or two later it seems) with the oil door in the front of the cab, a window on the back of the cab, larger diameter air intake tube (cab mounted) with a cab mounted single exhaust. I just cast some slam locks to put in the bottom corner of the doors, but I still need to come up with something for the side step ladders from the late 70's.
