What's the Difference Between...

...a "Pro Touring" and a "Restomod"?

I gather that both involve updates to engine, wheels/tires, brakes, suspension, and interior. Is it that the Pro Touring is more extensively modified, with a lot more one-off fabrication involved, whereas a Restomod involves basically bolt-on (more or less) modifications?

Resto Mod - Restored with some upgrades like EFI engine, newer trans and upgraded suspension. 

Pro Touring - Heavily Moded suspension, usually a new fabbed chassis, borderline race engine, usually with forced induction of some sort  and all the goodies to go with it.

Absolutely spot on !!!

Okay, I think I got it now. I've been calling a certain project a PT, but now I think it's more Restomod. (Actually, as a curbside/semi-slammer, I guess it doesn't really make all that much difference.)
