Can anybody give me an idea of what gear ratio a 73 Power Wagon 318 auto 1/2 ton 4x4 8-3/4 with locking hubs should have. I know it's impossible to know for sure with the info I gave but does anybody have a good guess. A guy is selling the rear for cheap but doesn't know the ratio he thinks it's a 3:55 It's about 25 miles away and I don't want to go after it if it's a highway ratio. I just plan to use the center chunk for my Roadrunner.
