Air bags or not...Need some advice...

[SWB]

Hello All: I'm new to the forum and a great knowledgeable forum it is, I can't quit reading. I'm a Hot Rodder from the past and the Air ride Technology is new to me so bare with me, lol Anyway My question is I have a 71 SWB 2WD that I getting ready to start on. It's going to be a driver of all seasons. I was thinking of a 3/5 drop and not notching the frame.

1. If I bag it do I still need drop spindles and shocks and will they holdup to the harsh winters we have time to time here in Illinois.

2. How do I set the height to have the camber correct for long trips ( tire wear )

3. Is it money ahead to just get 2 1/2 drop spindle w/ 1" springs and 5" springs for the rear.

Throw some #'s and info at me of cost going both ways. Thanks in advance..
