How rare is this car?

Nice find but I prefer Yellow:) . Mine has the stainless windshield trim already but someone did a crap job rebuilding my 273 so have it out now and am putting in a 360.
Currently stripping engine compartment and going to paint back to yellow. Have a set of
small bolt 14" rally wheels for yours if your interested - I went to the LBP Rallies when
I switched the from drums over to 73 disc.
