1966 new yorker factory 440 car, 489 casting number on the rear end housing, what spline axles?, trying to order parts prior to pulling every thing apart.

It is open. I am trying to order a clutch style sure grip for it, but don't seem to see any30 spline units that aren't cone type (non-rebuildable I believe). I have run detroit lockers before, but want something a little more laid back this time around.

Another good option is the Richmond Powertrax. Realtively inexpensive and installs into the stock open diff - not real difficult if you know how to set up gears.
