Help me ID my 18 Spline Tranny...

The premium money is in the stock 18 spline ones. ANY modification from stock is, in my opinion, going to REDUCE the value. If it has a liberty gearset, or hemi gears modified by liberty, theres no going back to a syncro assy. Those gear sets are machined, and have a dog ring slider deal welded to them. The old way was to throw away the syncro rings, and grind every other tooth off the dog teeth on the gear. I don't know if a new syncro ring would fix that, but it might work. All this was popular before jericos and other race 4 speeds became common. Even most nostalgia cars use a modern race trans these days....
