Post them! Everyone has their idea of what the limit of modification is. Some are strictly stock, some are non visual mods and some go hog wild. Most don't judge, if they do, that's their problem.
I'm a mostly stock appearance guy, I like the look of the first two years and although I don't mind small modifications, little things like large diameter wheels and low profile tires drive me nuts. I think to myself, how could anyone do that to a classic car? But that's just me, I'm not going to criticize anyone who doesn't think the way I do. I have a rear spoiler on my 68 and I'm sure that drives someone else nuts just like the big wheels drive me. My car doesn't look too far away from stock but open the hood or read my engine build sheet and it's another story.
You didn't try to make the Firebird into a Camaro, someone else did. Each to his own.
From what I've read the Houston guys are a pretty good bunch, I'm sure they'll give you a hand if you need.
Might give you the gears about the fake Camaro but roll with it.
