I saw those bits in Eastwood as well, and had seen someone use a copper spoon to fill in trim holes a long time ago. They are a great tool to have around, esp if you do alot of butt welding like I do!
I just went to Ace hardware and bought a 4"x10" sheet for about $4. Beats the Eastwood price all to heck. grin

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
