Changing rear axle ratios 4:11 to 3:73
I've got a 71 3/4 burb with 4:11s, the rear axle cover is a 14 bolt cover. I don't know what it really is Dana or ??? Drum is 11" X 2 3/4" at least.
Can anyone tell me how to determine what type of rear axle I've got?
Then the next thing would be can I put 3:73 ratio in?
