Sal, JCC lists them under Cougar sheet metal. I'm not sure what company makes them for him, it says Made in the USA.

John,
The only thing John lists is "full" (Tabco type) quarters and trunk drop-off's. If you are seeing quarter patch panels, please post a link as I can't find them (after looking twice, once after reading the thread the first time and just now again after reading your post).
Regards,
Bob
Sal,
Other than original sheet metal cut from a donor, Tabco is the only game in town. If you go this way, be prepared for a lot of trimming to make the inner edge of the wheel wells the right width, same for the taillight panel edge, Jamb area too if you use it, (I avoided this area like the plague), the valence attach area is all wrong, the edge bends are wider radius and the metal has less temper to it (softer, more easily dented, I imagine this metal makes them easier to form). My approach after observing all this was to use as little of the new panel as possible (as opposed to trying to graft the whole thing in), re-use on one side and fab on the other the valence attach area, build the quarter extension edges out to match factory radiuses and the like. It can be done (and well) but it is a lot of work. Caveat: The new panels out there are a new production run, not sure if any of my observations have been corrected, have yet to see one in person, mine were from an older production run. Donor metal is going to be expensive and expensive to ship unless you can find it locally (and live in an area that would have cars with good metal).
