Will the '68 Dart 225 run again?

Those conversion charts can be helpful...though from firsthand experience I can tell you 195/70r14 and 205/70r14 both fit on 14x5.5 wheels. Might be able to to do 215 width (I wouldn't see why not), but I don't know off the top of my head.

Glad to hear you can drive it! :)

Probably looking to go with these:

because they are cheap.

Car is not able to be driven yet...need tires for inspection.
