So -- you guys with classic Mustangs from the pre-unleaded era...

Do you have to do anything special to run unleaded gas without damaging the valves, etc in your engines? It used to be that people would add lead additives to their gas, but I'm not even sure you can get that any more.

Or is it kind of a non-issue now....


Reason I ask... well, if I was was to say... Sell the Cobra and buy a 69 Mach... is it something I need to know about?
