Hi, don't know if I can help out any, but I have 67 firebird that has a v8 vin but has a 3h stamping. I was confused how I could have a v8 vin, but have the sprint code on my trim tag.I am 99% certain that trim tag is original.Trim tag matches original color of car and interior, I checked the hidden vin numbers to make sure the vin tag matched and it does. vin # 223377u1xxxxx trim tag is 434 05a 67 22437 lor 15520 body paint tr254 z qq 2wg 3h Thanks,Tyson
