what gears were originally available in the 9 bolt for thirdgens? specifically, could you get a 9 bolt with 3.42 gears? I was under the impression that they were only available with a 3.45 gear. Am i wrong on this?

Thanks,
Eric

Factory supplied 9 bolt was 3.45 not 3.42.

Currently installing 3.73's into my 9 bolt (YES, it is a 9 bolt & YES they are 3.73's, not 3.70. I currently have 4.10 gear sets and new series 3 carriers in stock for 9 bolts )

They also came with 2.77 and 3.27. 3.70 gears were never offered in a production vehicle but were available from the GMPPC
