I'm not certain, but I think Chevs of the 40's has the paint you want. I ordered a quart of interior paint for my 53 from them, but it is possible the 51 would be different. I'm not sure.

I didn't use the paint I ordered. I think it was probably the proper color, but I didn't like it and went with a color combination of my own. I wasn't going for a 100 percent correct restoration, so I said what the heck, when people were still using the truck on a daily basis no one paid any attention to what color they used, the just put what they liked on, so why not do the same now.
