Here's what I've got. I'm running 69 front Disc Brakes, and 2nd Gen Rear disc brakes on a 70's Nova rear end (same dimensionally as 1st Gen FB rear end). Car is lowered 1 in. all the way around, with stock fender wells. I have a slight rub in the driver's side rear if I have passengers in the back and I hit a bump. This is minimal and I plan to fix by rolling the fender's slightly this winter.
The Wheels you are looking at I don't believe will fit on your setup. I bought my wheels form Newstalgia Wheel in 2006 for $1080 including a wheel installation kit, and insurance. The rears were more expensive since they are a "custom" size.
