There is an "old school" place that I've been taking all my vehicles to for almost 20 years in Glendora, California. It's called Bear Frame and Wheel. Gary is the owner and personally checks each vehicle.
This is an original place, they've got the pits in the ground in a circular formation with the central "tool room" and the offices built on top. In an ariel view it would look kind of like a daisy.
I've never seen a Pantera there, but he seems to be the go-to guy for hot rods and custom cars and trucks.
