I figured the P/S modification was a kludge, but it's the least of my concerns right now. I'll keep the shim in mind.
Ironically, I found the steering much scarier on the (partial) drive home than the brake feel. The distance between the gas pedal and the brake also scared the crap out of me at first, when I realized how easy it was for my big foot to pop off the edge of the brake and fly onto the gas. My braking motions changed entirely after that - now I move my whole leg to brake.
Mopar steel 14x6" rims? What would they have come on? Unless a Chrysler 5th Avenue M-body has a set, I don't expect to have much luck. Most junkyards that have old cars in this town weld the steel wheels together to prop the cars up in the yard. I've even considered buying one of these things out from under a car - it was a 14x7" steel Mustang rim; bit hard to come by and it hadn't been bent - and grinding the other wheel off.
She's staying radioless. I yanked the radio out of my '71 Mustang and put a factory blank-out plate on that. Radios are for listening in your house, cars are for driving.
If the passenger mirror isn't factory, neither is the driver's. They don't sit right on the doors at all to begin with.
