change the ring and pinion?

[twilson88]

I?m looking to increase the rear-end gear ratio in my 72 cutlass. The mechanic that does most of the work to my car says to do that would be a complete overhaul, estimated cost 1500.00. Can?t I just change the ring and pinion?

You could, but consider the thing is 30+ years old now and would need new seals and bearings at the very least. Plus there are compatibility issues in those years- some deep gears won't fit in some tall gear carrier housings without changing everything.

$1500 does sound a little high though, but price often depends on where you live.

As bad as I hate to suggest it, try finding a Chevy 12-bolt rear end to swap out drum-to-drum. You may come out cheaper and some of the cars came with them, so it's not complete heresy to put one in.
