Assuming the photos I view of this car on my computer screen are scaled correctly, the 'GS' & 'by Buick' emblems on the rear trunklid seem in odd positions - too far to the center and a little high. I cannot see close-ups of the other side emblems to take issue with them. Curious for a 66K mile car.
Those trunk emblems are definitely not in the correct location. Would be interesting to see what number and date code is on the "new correct 4BBL carb". I also wasn't aware that GM made a 4 row radiator that would fit an "A" body.
