Fact: it is possible to improperly set the load by having the lever out-of-place when the load is set.

Ray, I've been looking for the "old type" to little avail. My local body shop guy told me I might be able to get them through a specialty automotive catalogue, but he said he paid nearly $75/ea for them. Economy is not worth your safety, but there's little choice out there on the racks. I've been using the lever-locking jackstands, but always get concerned about accidentally knocking the lever with my foot when I'm under the truck. For that reason alone, I throw a wheel or two under the truck.
