WTB 4.30 or 4.33 12 Bolt passenger car gears any date

[jbtech]

Update 10/31 4.33 GM gears found. They sold them over the counter for performance applications. Learned something new!


Update 10/30 Looks like GM did not make 4.30 or 4.33's. So any aftermarket good used gears will be ok.

Looking for a good used GM gearset for my car.
I want to swap out my 3.55's.
Not particular on dates just looking for a reasonably priced original GM set if there is such a thing.
