SLO- very cool. You should keep it as close to original as possible, not mini tubbing, etc. These are rare cars regardless if the big bumper is a turn off or not to others. I'm OK with it, it's history and progression. Wouldn't be here if we hadn't gone there. I have a set of factory GM slats for the back window, not manufactured by GM but authorized by them, came with my car when I bought it. Are you looking for any parts?
I know what you're talking about as I own a 74 Z too. I had that switch fail on me in a wendys parking lot, and I was able to talk 1 block away and get it in stock from the parts store/machine shop I later worked for. Im still too this day flabbergasted that he had one. I disabled it later that day, but its still on my fender. The factory engine is the same as the 73Z28 and corvette, and the last of the pre smog engines. heres my car:
