First you should probably figure out how your going to use the car the majority of the time and what you can live with. Personally I enjoyed the 3.08s I put in my 58 Chevy, but I did a lot of highway driving.

If it was me, I think look in the local wrecking yards and see whats available locally. The 55-64 third members interchange and I would think you would be able to pick up a complete unit cheaper than the price yopu got for just the gears. Additionally, that way your 4.10 gear set is still intact in case you ever want to put it back in.

Generally the break down of factory gears went pretty much like this unless the car was special ordered.

55-57 3 speed overdrive 4.11
55-64 3 speed overdrive 3.73
55,64 3 speed standard 3.55
55-62 Automatic 3.36
62-64 Automatic 3.08


I went from 3.36 to 3.08 at one time and although i saw a couple of hundred RPM difference at cruising speed I did not notice any change in gas milage or preformance. I would say either the 3.08 or 3.36s should work well for you.
