I guess it depends on where you are...Ch#vy 12 bolts be plentiful down here!

I have a 72 parts car with an O-type 12 bolt 3.08, but gears are what's REALLY hard to find. I'm currently running an Olds 10 bolt with 3.42 posi. My builder (an Olds racer) says it will do just fine behind the mid-12 second street/strip 455 he's building me.

Talk to California Differential in Fremont. They have a good rep.
