You can still get the lug wrench and breaker par that came with them at Napa. Mine still has the one that came with the truck, but it is identical to the one at the store. You'll just need a solid 5# hammer &/or a piece of heavy wall pipe to get the oomph! behind it to loosen properly torqued wheels (I had to take mine, hubs, drums, and all to local tire shop to get them off).

The ratcheting screw jack that 55 shows can be found here & there in junk shops. Have seen a couple myself, they are solid units.
Anyone know if they are still in production? I'd rather have one of these in my rig than a hydraulic jack if I can find one.

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
