I love those AC models. I either want my next truck to be an AC model or cannonball with a 6-71... Oohhh yeaahhh! Now youve got me drooling on the key board. And by the way, why dont I see pics????
The A indicates 39 and up. The C indicates conventional cab. R indicates Tractor. My book only shows R and W as being the fourth letter, so Im not completly sure what it is. Being that its a Tractor model, its a 520 series or bigger with a 308 6 cyl and a Clark transmission as being the stock drivetrain.
You better get some pics next time!
