A = the metal rivets that hold the , nylon roller on the window winder lift arm
as mentioned B = nylon rollers
as mentioned C = plastic rivets to attach , winder run channel to glass
D , side glass up stops , there is a hole in the bottom rear corner of the front side glass , this stop just simply pushes into the hole , then a phillips screw holds it in place . this is what I can't remember , the side glass up stops changed some time , some years don't have this hole , mine does & has this set up , so not sure if cars up till a SPD of late 68 had them , or cars from , or early build 69 cars with a SPD late 68 & later years did

long story short , around the E series model year they changed the up stop set up .

so you may or may not need D
the nylon roller wont stretch over the rivet A , so the A rivet on your window winder arm will need removing & new roller & rivet fitting together at same time
