Had a little time to tinker with the heavy Chevy. Took her out for a madden voyage and the tires rub, not to bad though. With my calculations I believe 650x20 will work. But I'm going to first use a flap disk and angle in some of the outside tread. That should take care of my steering issue.
Bought an EZ wiring 4 circuit harness. Don't have a clue about wiring. Spent most of the day separating the wires in the harness for in dash and engine compartment. I believe this will make my life a little easier. I have not installed any of it yet. I have only removed every bit of the old hacked up harness and random wires. I ordered all new switches due to the fact that they are cheap and working new is usually easier. I have attached a few more pictures of my progress.
