OK,I have a 1932 Nash and the wheels share the same bolt pattern as some Dodge's, six bolt pattern. So, my Nash has a stump pulling gear ratio and is really maxed out at 45-50mph, not that I want to turn it into a speed demon, I just want to rear end that will allow it to handle 55 mph without stressing the engine so much. A junk yard near me has several mid to late 40's mopar cars just need a place to find gear ratios to see if they will work.
