Regardless, of how people feel about the wings. I think people need to take into serious consideration that all of these trunk lids are rare as hen’s teeth. Especially, in good unmolested condition.
One day we might consider selling our car. Despite, thinking we will own it forever. We all know **** happens in life. Emergencies, life changes or we might decide on something else. Most potential buyers know the rarity of these cars and certain parts. Why risk the value of your car by hacking up a rare part that doesn’t need to be altered ? It’s honest leverage that you are freely handing over to a potential buyer one day. That may not like it or use it as leverage period. This will allow people leverage into not giving you nearly what the car is worth or potentially scaring buyers off completely. It’s not worth it to me, even if you like them. If it was 1972, have at it. No big deal. You can find another one.
You asked for opinions. The little go wings look horrible on B bodies. The wing size doesn’t match B body style or size. Trunk spoilers, look cool on B bodies that are rectangular in shape. It looks like someone bought these other wings from Walmart, in the year 2020. Threw it on a 50 year old car. With 50 year old styling. The square shapes of B bodies are attractive. That’s what makes them appealing to people, today.
But, my opinion. Your car.
