Greg - Wolverine doesn't offer a 1"x6" anymore. The closest is a 1-1/2" x 6" and I'm pretty sure it won't clear the foundry mark. For my tractor, I think the 3"diameter will fit and I plan to make a 3" dia carboard template first to see if it will fit with one on each end of the oil pan, allowing the foundry mark to lie in the middle between the two heating pads.
