RH-5 and rusty as well. I've worked on plenty of them back in the '70s & treated them like loaded gun!
Wouldn't touch one in that condition.
You're talking about replacing the tires on them or just in general? Anything I need to worry about in taking them off the truck?
I don't intend to keep these, but I was wondering if they might be valuable to someone. Likely not it sounds like.
