Air ride?

[jarfly]

So I got a 77 that i'm debating on putting air ride on to get lower, Im not looking to lay it out, So thinking of staying on stock spindle, Has any one had any problems with this? Kind of stumped on my rear set up, I will be pulling with this truck till I get a f/s 4x4. Not really wanting to run links, so debateing on flip kit and pulling leafs than add the bags and air up when needed.
Hopeing to bulid own mounts etc to save on project cost.
When you do the lca, do you recess the bag mount in the arm or flush with top?
