I ordered steering box lube from penrite from WWW.Classicautolubes.com. I put it in the steering box, and haven't driven the truck yet. It seems to be working. I am getting a little leakage, but I think that might be a little oil that was left from earlier. The fellow that has this site seems to be extremely honest. I e mailed him, he sent a message back telling me what he thought I needed, I sent him a return message, and he sent the lube before I mailed him a check. They also have other oils expecially for older vehicles. Expensive, but seem to be qualilty products. Allen
