Welcome Mark ! Sounds like some nice projects you've got going on. Would like to see some photos.
I'd recommend checking Lloyd's https://www.camaros.net/forums/133-b...post1783202815
and Chick's https://www.camaros.net/forums/133-b...stored-78.html
build threads as both guys have done extensive research on originality and have done some top notch restorations.
Also, CRG's "Originality Forum" Originality
is a great place to see photos of unrestored, unmolested, survivor cars.
Here's what I can tell you from my limited experience;
The leaf spring tags should be near the front eye just behind the mounting bracket. I've seen survivor photos like this. Most restorations have the tag at the rear, near the shackles, so maybe either is correct, I'm not sure. I did notice Chick's at the rear. Would like to hear him chime in on that.
I believe coil spring tags were generally on the second or third coil from either the top or bottom. Have seen them both ways.
Disc brake backing plate sticker at the top, near the spindle. You can see how Lloyd placed his.
GM door sticker was factory installed on 67's only. They may've been dealer installed
on a few 68/9's IMO, but obviously there's no hard evidence of that.
Coolant sticker was only on Canadian sold cars (First Gens), from what I understand.
No "Caution Fan" stickers, period!
Probably the most common, incorrect sticker used on First Gen Camaros.
Hope that helps...
