68 Camaro Air ride??

[camaro2nv]

I bought a 68 Camaro a few weeks ago. The car was blasted and painted. Being a paint guy the car is FAR from what I want. I want to build a pro touring car. I have many plans to mod this car from the ground up. Ive always wanted to build a Camaro but never had a chance. Ive modded many Cars, bikes they just turned into projects. I guess those projects were good for me because Ive learned a lot about modding. Now I just have to learn about 1st gen Camaro stuff. I have ideas running wild,lol. One of the main things is I want is a air ride system. Question is should I start with the stock sub frame and just mod the control arms ect. Or buy a subframe ready to roll, thoughts????
Heres my project
