833 trans, OD

I know the 3.91 is fun, I would find a complete 3.23 set up and swap gears.
I used to swap 3.91 in after work on Friday and on Sunday morning swap the 3.23 in.
If you are smart you can extend the brake lines, so you just pull the axles out a few inches, unbolt the center and rear u-joint.
With a drain plug on the housing, rear end swap is under an hr swap.

The gear ratios really suck in an OD 833, I have ran that trans, and prefer the std 833.
I have an A body OD 833 but shipping to AZ would cost as much as the trans is worth.
