[67chevy1series]

my uncle has a 52 and I ordered the wrong tail lights for him and they wouldn't let me return them because we had them for about 6 months before we went to go use them and realized they were the newer style. so just want the money back that we paid for them. there 40 bucks new and that's what I would like for them plus shipping. they come with the harness the buckets with hardware for them, brand new bulbs, 2 gaskets, stainless steel bezels and new lenses red in color heres pics
