Besides the upper control arm mounts and welding the seams is there anything else you are doing with the stock sub?
I'm just about to embark on swapping my stock sub for another stock one I sourced so any hints or ideas are appreciated.
I really appreciate what you are doing with this Camaro with vintage TA tricks paying homage as opposed to just

and waiting for the latest and greatest mail order package etc...

Not that there is anything wrong with that approach...
Just a quick image copy/paste out of admiration...
My car was originally gold so the Smokey theme has always had an appeal to me besides the obvious nod to the icon himself. Yours is going to be the ultimate with that motor.
