Hotchkis coils?

[JTS71 Mach1]

Good find on the replacement panel, sounds like a good price as well. Don't know about the emission equipment in the trunk??? as I remember there was a small evaporative canister located in the engine compartment, down in the right front corner down and out of the way. Don't know I ever saw anything in the trunk? Yes there should be a valve somewhere in the line It will look a lot like a threaded valve stem, similar to the one used on motorcycle wheels. Glad you're making progress, it sounds like you're making a good thing better. Good Luck.
