Application options - - air ride, chassis, s10 1948 3100

[motown]

I have a 1948 5-window I have began restoring. I've been in contact with 99 to Life who has given me some great feedback. I would like some recommendations for my specific application... First, I know the S10 vs camaro (etc.) clip vs. Mii debate will get mixed reviews. However, here is what I do know that I'm tentatively planning to do... I want an air ride suspension (lay running boards) , manual transmission, and will likely go with an LS3...

I currently have a stock frame with what I think is a 70-72 camaro front clip... Would I be better off to try modding what I have to work or would the S10 option be better in the end. 99 to life said the camaro tends to be on the wide side which I have heard. But is there mods that can be done to correct that? My fab experience is very novice but I'm willing to learn. Any input would be most appreciated!
