Wheels are very much an expression of one's self... and everyone has their own tastes. Me personally... I would go with some bitchin old school mags on your car... and maybe mickey thompson indy profile tires to complete the vintage look.... or re-treaded cheater slicks!
For wheels, stay with 15 inch and run something vintage, like the old slotted mags, vector or turbine mags, old torq-thrust mags. Leave the 16" and larger for the newer rides. Your car is a '68... run something that is era-correct.
Also you can never go wrong with 15" wheel vintique rally I's!!!

Also don't forget the ol skool Cragars:
