Overflow bottle

I don’t but nice. I used the 73 power train in my daughters 72 Duster but the tank and charcoal canister seemed like it should be saved for just this purpose.
Got a lot of 73+ parts on my 72. Still learning what all I have. I know the front suspension and rear axle for sure, and of course the center caps aren't correct either but I like em better than the acorns style.
