Some refrence details on the long and tall hood 700 series macks.
the Rubber duck Truck was a 1977 RS700L (Mack Western) This model ended in 1978 after the Mack Superliner was introduced. The RS/RL700s were aimed at the western truck market with the use of much more Aluminum components for weight savings and engines much larger than a standard east coast R model. A standard East coast R model was basicly all Steel nose to tail and powered by Mack diesels. The early western Macks (1968-1973) RS/RL700s have the cab sit lower on the frame like eastern macks. after 1973 the sat up higher off the frame and the hood is taller for better cooling and larger displacement diesels . You will notice Izzys hood is taller than the standard R model hood on my Green 6 wheel dumptruck. His hood is also longer. Western macks used aluminum fuel tanks without the indent step that eastern R models had. you could get the Western fuel tanks in 50gal all the way up to 126 Gallon. Only the 126 gallon tanks used 3 straps and the rest were all duel straps. Mack westerns also had a industry standard frame width with straight rails. they were slightly wider than a East coast Frame and did not spread up near the engine like east coast Macks do.
if you need any help just ask as I own the real thing
