I am curious how you sealed up those guys from the elements? I was considering doing away completely with the back hatch glass as well. I think it is overkill and definitely causes cabin temp issues. Being that the car is well insulated the heat just gets stuck in there I imagine. I think this is one area of the car design that needed a major upgrade. Most modern cars don't have to worry with there AC systems but Centurions don't sport these luxuries. I think you nailed it with the louvers CJ great job
Every year the car just keeps getting better and better it is a masterpiece
