I'm putting my interior back together. When i took it apart there were really big plastic washers behind all 6 handles. I opened up the stuff i got from mustangs unlimited and there are 4 large plastic washers and 2 big springs. which 2 are supposed to get the springs and which direction should the springs face. Or should i just have 6 washers and the springs not used. The car is a 67 convertible.
