Re: Starting the overall replacement of front suspension today :-) drop time.
3.08 was the most common for 350 v8 auto trucks. Same with 400 BB in a 1/2 ton. At least in 71-72.
3.73 was most common in the 6 cylinder. The numbers will be stampled on the ring rear OD. Clean it of and look you will find something like 41:10 which would be 4.10. Also should find GM part # and a date stamp.
2.73 wasn't very common until later in the '70's.
