Let's Talk 67-69 Barracuda 17x8 rims

Ok, now that 15" RWL letter tires are becoming obsolete, I'm considering "modernizing" my Barracuda by moving up to a 17" wheel. I do know that most say a 5" to 5.5" backspacing is required to get a 245/45/17 on the front (will anything larger on front fit?) and a 5" rear backspacing for maybe a 255/50/15 rear tire.

Has anyone researched 17" wheels for our Barracudas and found any viable options? I would like to keep a polished or chrome wheel on it maybe in a 5-spoke design (could be straight spokes, curved spokes, etc.). I have seen in a few Mopar magazines featured cars that look really good, but they never go into the details of backspacing or modifications that needed to be done to make it work. Obviously, we don't have any wheel dealers around here that stock 4.5x5 bolt circle (yes, I have the 73+ disc brakes on the car) 17" rims that would be willing to like me try them on the car.

I'm not looking on spending a fortune on rims. If there are "affordable" options (like the torque thrusts) that are out there, that would be best. OH, of course, photos are GREATLY appreciated!!!!
