Does anybody know how much of a difference there is in the cab floors on the 300 series vs the 100 & 200 series. It doesn't look like much, but the tranny hump definitely looks lower..... Mark D. 1968 W200 Sweptline 1969 D100 Utiline 1971 D100 SE Sweptline 1993 D250 Club Cab Sweptline 1986
The 300 trans hump is flat and has a massive cover that goes up the firewall. The floor pan is shaped accordingly. The steering wheel penetration in the floor is a different shape and location. There is something different about the gas pedal.
Ben had to convert a 300 cab to the 100 version when he restored his HPP truck. I sent him some patch panels to do it.
