What Front Suspension Do I Have

[JGross]

I just purchased the 65 short fleet and was told the front suspension was set up for air bags. I plan on installing springs but I know very little about suspensions so here are my questions:

1. Do I have to replace these control arms or will they work with springs if I cut out the lower bag mount?

2. How can I find out what brake calipers will work with these spindles?

3. How can I tell if these are drop spindles or standard?

4. The rotor bolts are 4.75 inches center to center and 5 inches center to outside. I think the bolt pattern is 5 on 5 in. Is this correct?











Thanks in advance for you help
