For Nam, use 24087 semi-gloss. Make sure it is the old FS 24087 as the new FS 24087 is noticably lighter, yellow-brown compared to the FS that was in effect in the sixties and seventies. For a close match using the modern FS, use 24084. I used Randolph 24087 on mine and it looks right to me. I got my rattle cans from Peter DeBella Jeep Parts and he has gallons also. I called Randolph and verified it is true 24087 and also cross references to the modern FS24084. Just be aware that rattle can paint doesn't have hardener like you would add to paint to be sprayed thru a gun so even when cured, the paint is a little soft, ie, scratches easily.
