Thanks Jim, yeah I have a 4100 which I purchased overhauled (I won't say restored) as I've since found out.
I'm not sure exactly what to do with it, from knowledge the finish is butchered once it's been blasted like this one has. I'll run with it until I can find a good restorable candidate, it's not the only thing I need and not really in any rush for it as I'm still a sheetmetal work stage, the tail end of it at least.
As far as gas prices, yeah it's expensive but an expense I can control (just don't drive, lol), unlike cost of Mustang parts, shipping and a struggling Aussie dollar.
