Barracuda Wheels

Rob if your Barracuda is your avatar, it looks pretty good as is but, I'm with you on the muscle car look.
I'm 65 and that's a good look for me too.
Your Barracuda should fit some 235/245 60 14s in the rear if you can find them. The 15s you are talking about are out there, you just need to get the correct ones that fit your wheel mounting bolt pattern. Your hot rod looks great set up many different ways. Good luck.
