Rezzing and old thread since I really got a kick out of it and was looking for a place to post a Website link for Decals and Battery toppers.
I bought an Autolite Sta-ful decal set to stick on my blank side Interstate battery in the trunk. No toppers though just didn't like the black battery case sitting on the trunk.
This vendor is in Belgium and is fair on shipping rates.
