Do I need one of these to operate the doors inside the box and maintain the proper vacuum. Again, I am trying to sound smart here, but not sure this is describing what I need. I looked at my fender well underneath the battery tray and see no holes for bolts to be threaded into like pictures in the link above. My car is a 72 RR, 400 with ac and a manual 3 speed on the floor. If I do need one where can I buy one. Next question, I had the car painted and while it was being painted I lost the door cylinder lock, clip and the little rod that goes from the cylinder lock to the door mechanism to unlock the door. Can someone help me out with where to replace those pieces too?
Thanks for the expertise advice in advance.
