Possible new project 1987 D100

[79 Camaro]

I haven't seen it in person yet but it looks clean.
My question is are there much for upgrades for the suspension? Lower it a bit like a 4/6 drop.
It's a 5.2 with air. Bench seat. It's a "older" resto from AZ.
I've never done a Mopar so it's a bit new to me.
Any web site suggestions would be helpful.
