I have one that I pulled off a 72 Satellite and used on my 69 300. i mounted it to the left side rotating headlight bracket, fit great. I still have the overflow bottle and would let it go if your interested.
This is a lot like I mounted mine in my 69 300. The bottle I have has a built in overflow, in the neck, that emptys at the bottom of the bottle. I never did see any residue anti freeze on the ground.
My 68 Newport but it was obviously an add-on as both of the screws don't match and it's on an angle instead of mounted straight.
Still better than letting it vent on the ground, in any case. Don't know which owner added it.
