Ring and pinion ?
Buddy has a ring and pinion that he says is for Chevy truck, numbers on the ring are 2 GM 3988517 11- 41 5 76 and numbers on pinion are 3988516 11. 41. And 5 76, I have no clue how to figure out if they are for 12 bolt Chevy truck, any help would be appreciated. Thanks

Re: Ring and pinion ?
41 divided by 11 is 3.72727272727 or 3.73 ratio rounded up. They were made in May of 1976. Google suggests the part # is for an 8.5” 10 bolt. They will work in a truck 10 bolt, but in 1976 GM wasn’t putting the 10 bolt in a truck. Yet.
