so no one has heard of this ? I bought a 1949 route van parts book ad no mention of 4.30 ratio, anyone need this manual ?

I'm running wc51, already put 4.89 half ton and early 3/4 ton ring and pinion in. Now I heard at a recent show that a 4.30 was used in dodge route vans and that it fits the wc. True? false? Any help or experience? ran rt 66 last year 2,000 miles want a little more speed. Next year we doing rt 30 the Lincoln hi way.
