Dave, when time allows, could you post some weld parameters for the "back from the dead" Mustang ? I see you're using a couple of different machines, and wondering if you "stitch" with that as a built in function, or just trigger and whip the gun.
Your latest,....I can tell you that it took FOREVER to get back to where I really wanted to be (N.O. La.) once, in a virtually identical car.
A little prone to vapor lock if you didn't open the hood, right off the road.
Other than that, solid as a church,....and more than adequate for gettin' state to state.
