Another Valve Question

I'm going to run these old Master Image Custom manual valves that I've had sitting around forever. The problem is that I only have two and I don't want the truck leaning on turns. I'm reaching out hoping someone has a couple they are willing to let go. If so let me know, I'll take one or two, whatever you have. I have checked around and google and ebay have turned up nothing.

Man I haven't seen any of those in a very long time.
