I'm going to buy one of those little torches. They look like what I need to concentrate a flame/heat in a small area. Still trying to locate a wide blade that will work with an impact driver. Went to Wholesale Tool and they didn't have any. Still soaking in PB, but will also buy some Kroil.

I'll just keep soaking and trying with what I have until I get the new toys- I mean "tools".

Thanks everyone for the input. Looks like I'm on the righ path, just need to keep going.

Hard to believe they didn't use at least a Phillips type head on these.
