Gary,
Tanks look great! Did you drill the hole for the screw to hold the brass pocket, or does the 20K tank have a screw in that spot already?.... ? I don't think the 25.5 has a screw there, but I don't have one to look at rite at this moment..... The white tank with the conversion looks better...but the black tank doesn't really look too bad stock in your photo...lol
