1958 A-120 4x4 re-gearing differential?
Hi folks - this is something of a continuation of my what is the top speed of an A-120 4x4 thread...
I am thinking about the possibility of re-gearing my differentials. I think the front (an FA15 with 4.55 ratio) is essentially a Dana 44 and I can find the ring and pinion set to bring it to a more useful (for me) ratio of 3.73.
The rear I am scratching my head about! It is an RA10 (according to my Line Setting ticket) and it currently has a 4.77 ratio. I have attached photos.
Does anyone know if there are ring and pinion sets available for this rear axle/differential? Were they ever made in 3.73?
