Check out my pics. My father had them on his 71 Cougar. I like the look.
I can confirm this but pretty sure he only needed 1/2" spacer . Did not need longer studs. Not fitment issues or rubbing. Came off 2003 Mustang Mach 1.
I woudn't wait a heartbeat to get those wheels. They are discontinued and they were pretty nice when new - I've had a set of 20" of the same Wheel replicas. Those are missing two of the centercaps, but they were snap on if my memory serves me correct. I would use with those 18x9 6.5" BS only an one inch spacer in rear to achieve a 5.5" BS - or to position you like the best. I would use Eibach style pro spacers which are bolted directly to the hub. To the front I would probably use a little thicker spacers to get the wheels closer to the fenderwell.
That aint bad price for the wheels, I would grab them asap. Those 20" Magnums are the only wheels I've regret selling them. They were sa-weeeet! Magnums look so right with these big ponies. Try to buy 18" magnums now - they run minimum 400 bucks a piece.
Thanks everyone for the advice & guidance. I'm going to try to contact seller today. I planned on buying the 17in American Tire wheel this same style but these 18's seem to be a great deal & I love saving money.
