I am finishing up a WD45 myself and I went with the vinyl decals. It was kind of pricey at $80 for the set, but every decal needed for the tractor is in there and they look great. E-mail me if you want to know where I purchased them. It seems when I mention a competetor on this site I get poofed, even though I have purchased through these guys before.
Also I have never gotten the page for Wacker Decals to work, but would have really liked to have seen what he has.
