Differential numbers decipher please
It is a 14 bolt full floater pictured below. Only thing I know about it is, it is not stock to the 72 C20 it is bolted to right now. I would like to know the gear ratio and anything that you could share looking at the numbers and pictures. Thanks!
I took the numbers from the area pointed by the red arrow and they read: 1 GM 3977334 10 41 4 76 I plan on jacking it up sometime and count tire/driveshaft rotations but it is not on stable ground right now.
