Spell Chek always works when you don't want it to. It's Jay Cee VW enterprises or near that. They a lot of high quality VW stuff. The one I really like is the crankcase plate for VW's. It never leaks. "O" ring instead of a gasket and each 6mm stud gets an "O" ring as well. Magnetic drain plug strong enough to pick up a hammer too. Just high quality things like Vintage Speed makes.........Bruce
