Wheel size for 1967 Barracuda

Hey Scott, welcome to fABO. Your rallyes search can take place right here, there are plenty of guys selling OE sets of rallyes. For accurate info, small bolt 4” rallyes only came in one size, 14x5.5”, and I believe the backspace is 3.75”. If I’m not mistaken, member “pauly” had a nice set with tires for sale here just a week or so ago. Look thru the for sale section under wheels and tires, I’ll bet you’ll find some!
