Some years back I had a '47 CJ2A, and am currently considering getting another (a '48). My recollection is that the stock gearing was somewhere around 5.13 or so, and I'm wondering whether it's possible/feasible to replace those with maybe a 3.08 or even 2.73 set for better mileage and the possibility of doing highway speeds. Are parts available? Can it be done without swapping axels? Thanks.
