Airbag guys have any comments?

[peltjd]

I'm installing air bags on my 65 C10 and then doing my buddies 66. I've researched and think I have it figured out. Here's a run down. Comments and pictures if you've done air bags yourself are always appreciated.

I'm doing this:
Remove the bed.
8" step notch
Rear bags (2600) mounted directly to the frame (notched for air line) and mounting directly to the trailing arm. No cups or plates.
Tank (5gallon) and compressor (Viair 444c) mounted to frame or custom cross-member
Compressor wired with 4 gauge wire
Air system plumbed with 1/4" line
Reinstall bed (notch bed floor or raise it)
Controlled by Air Lift dual needle manual switches under the dash
Font lower control arm cupped with 2600 bags mounted to upper control arm by a plate


Questions:
Will my tire (235/75R15) fit in the front wheel wells?
Will I need to change my shocks?
How deep can my a-arm be cupped?
