1968 Plymouth Barracuda

Woke up this morning to a UPS truck try to make it down my slope of a driveway. "Got some new tires for ya" WOW I ordered these on Monday with standard shipping. (2) 15"X6" Cragar S/S fitted with 215/60/15 and (2) 15"X7" Cragar S/S standard offset with 255/60/15. Looking at the tire size in the rear I was a little sceptical if these will fit withoout and travel problems. They bolted right up with about a 1/4 gap between the inner tire edge and leaf spring (stock location). I plan on doing an adjustment to the torsion bars later this week or weekend. Any ideas?

You really have to see this in person to get the effect but I'm not going to complain the car pictures well. LOL look at those flat *** leaf springs!
