ok.

After reviewing what I found, that second picture (if I am seeing it correct) looks to be a pre-1973 fender.

Hopefully this works:
(images have to be smaller, or they are scaled down by the site)

This is a pre-1973 fender brace - note the two mounting holes for the inner fender (circled):


This is a post-1972 fender - note the two additional holes for the fender brace (circled) - they are also in a slightly raised pad so that the cage nut will not touch the inner fender:


This is a portion of the last picture beside a 1973 fender which is using those two holes;
I believe that this "leaf spring" style brace was from 1973 through to 1976, after which it was made to be much smaller (and only used one of the holes - but both holes remained):


Here is an image of the bracket included on 1970-1973 fenders to attach the valance (I found this image in another thread here - please note that it has been shortened/modified):



I will say this because it is worth repeating;
The only times that people here nit pick an early car having later fenders (myself included) is when a cream puff type car presents itself - and is presented as all correct (presumably in order to get absolute top dollar).
I'd think that well in excess of 95% of car show spectators would not notice this.

As an example of how little details are missed, the one time I was at the Trans Am Nationals I spoke to a gent who just restored two beautiful 73-SD455 and 70-RAIV cars;
I asked him why he had the wrong floor mats in the 73 - and I seem to recall that he was quite surprised at me having noticed this.
Many people don't notice little stuff like this.

Just look at how many second gen cars are running around with colour matched columns, and black formula steering wheels! (the column and non-formula steering wheels were always colour matched to the interior).
If most people don't sweat steering wheels, why spend time sweating an original versus a replacement fender?
(but if you have the time, and want to find a original fender, more power to you.)

I hope this is found to be helpful to someone.

Here's another vote that the fender in question is a service replacement Firebird part for 1970 and 1972 applications. The square holes in front of each hood hinge bolt location is the dead giveaway.

I dug out one of my valance brackets I cut off my original fenders (the other one is tacked onto a later fender that I used on my car for a several years).

Nacho yours is a correct 70 or 72 Bird fender.
If you can decide what the original color matches up to comparing 1970 and 1972 color charts , that might narrow down which year car it came from.

But its not an issue to worry about.

It sort of looks like verdoro green , I think it was available on 70 Birds .

I got 1 of these it's straight but has a little rust.nice to find 1 more drivers side. I believe it's dated 71. Are formula fenders dated could not find any marking on My green fender. I apologize if this is going off on a tangent from original thread I'm still learning and as of 2 years ago I didn't know anything about dating or 1 year only stuff. I built 3 from.rollers and mis matched parts that I could find at junk yard as a boy like dad taught me. I really like junk yard trips. My dad and I would drive around looking for the parts I wanted to add when I was 13. I wanted the rear spoiler to the 1970 formula and it took us 3 Saturdays to.find a ta. Im.blessed to have my dad's car still.

OPH, Bruce, Baron, Jonny, Nacho thanks for sharing that info.

At the swap meet I was holding the fender, inspecting, taking photos, and trying to keep my sunglasses from falling off. Multitasking was wasted because I missed the critical fender details and dropped my sunglasses.

Somehow I figured the 73+ raised section with 2 holes for brace wasn't there. My pic seems to show one of the two holes (hand covering area.. doh!)

I didnt take a photo of the front valance attaching bracket, but I don't recall seeing the bracket.

Oddly, I walked around and all day and this guy had the only Firebird fenders I saw. Driver's was $150 and pass was $50. I saw minor rust, no rust perforation, and no plastic filler. That seemed to be a good price considering the condition. Wanted to grab them due to low cost, even if not correct for my year, as spares.

In the end I couldn't recall the seller's location and left without them.

Nacho to me that green fender looks really nice.
