NOT MINE but with an hour from me....Says 71 GS vert Stage 1 https://lafayette.craigslist.org/cto/d/carencro-1971-buick-gs-stage-1-convt/6871189178.html
If it were anywhere near me I would already have it on my trailer. Worth every penny of a restoration.
Life's not fair man. Timing is everything. I have a 455 to drop in too. One small problem though. No money for car.
I never understood the notchback bench seat philosophy with a 4 speed. When I drive a stick my hand is always on the shifter. No time to use armrest..
The 'GS' and 'Stage 1' left fender emblem placement look spot-on, If that is an original correct fender, just another clue ...
