Did you figure out the tire size limitation on the front from the K-frame? It was quite easy to put the 275-35-18s in the car in my case with the stock stuff, so was suprised to see such narrow tires.
I've been running an 8" wide wheel with a 235 since I put the car back on the road with T-bar setup. I'm sure you know how hard it is to find an off the shelf wheel with the proper backspacing (for the front and back). I was wanting a 9" wheel for the front, but the ones I have weren't available with the proper backspace. There are no limitations to running a 9" wheel on the front. In fact, I'm planning on having these wheels widened to 9" so I can run a 275 tire. The tire will contact the frame rail before the tie rod contacts the wheel.
In reality, the adjustable LCAs would make it easier to source wheels since you would be able to pull the hub in, negating the need for a 6.5" backspace wheel.
