I'm looking for more information on the RPO 5.43:1 optional gears offered for 1 1/2 ton trucks in the late 40s'-early 50's. Does anyone know what part number the ring and pinion are? Any idea what the RPO code is for this option?
Any chance that someone knows where to get these?
Thanks!

The reason I ask is I found a website that has 5.43:1 gears for 1940-1954 1 1/2 ton cab-over-engine models only, and the part number is: WX2286A-7A
I would assume that this would work on my 1950 4400 1 1/2 ton, but I figured I'd ask first.
