Once the paint has had plenty of time to cure, you are now ready to reassemble with the new pieces. You could remove the vent window, disassemble and paint the trim black before you clean your regulator and rollers. That way it will be drying while you are working on something else and saves some time.
First, get the jar of Vaseline you keep next to your bed cause we are going to need it to get the rubber in.................................................................
OK, back on track......
Coat the entire inside part of the bottom of the seal, between the two rubber flaps, with Vaseline. Don't be greedy with it either. I coated the rubber strip in 1/3 sections so I didn't have Vaseline all over the place.
We are going to start inserting the seal into the metal frame at the bottom part of the frame where the frame pieces make a 90 degree.
IMPORTANT INFO HERE
If you look at the inside of the rubber seal, the area you put Vaseline, you will see some depressions in the rubber in the same location the rivets are on the frame. You can use these as a guide while you are inserting the rubber to make sure you have it in the correct place in the frame. Kinda hard to mess this part up, just pay attention.
ALSO, you will notice a slit in the rubber at the point the stud at the base of the vent window goes through. Just another reference point. Lastly, you can test fit the rubber in the frame and will notice the cut out in the rubber that is made to go around the bracket that the first rivet was in. Just take a good look at it all and make a mental note of where the rubber should sit as you work your way around.
*****This is the hardest part and was impossible for me to take better pictures of the process since I was flyin solo that day.****You will notice in the next 2 pictures that I am holding the rubber seal at a slight angle to the frame. This is so you can push one side of the rubber into the metal frame while you are pushing the other side into place using a screw driver. Your goal is to put both rubber flaps around the frame as you work the rubber in.
You will have to work the rubber into position inside the frame in 3/4 to 1 inch increments using your screw driver tip. Push in on the rubber with the tip of the screw driver as you use your other hand to help press it in place. It will take a little bit of practice to get it done, but you will have it figured out by the time you complete the other side. Make sure you keep the rubber at an angle so one side is already "pre-inserted" and all you are really doing is "squeezing" the other side in place. You will begin to "feel" and hear the rubber slide into place in the metal track as you work your way around. Getting the bottom part of the rubber, up to and around the bend, is the hardest part. It takes a little extra time, but once it is complete, the 8-10 remaining inches are a breeze. TRY NOT TO GET FRUSTRATED WITH IT AND WALK AWAY FROM IT FOR A FEW MINUTES IF YOU NEED TO. The Vaseline will help you a lot here so use plenty of it. It won't hurt a thing.
Work your way around until you seat the very top part of the seal where the frame comes together. Take a break and drink a cold one. You got this covered and are on the down hill side of the project. You will be rolling in piece in quite before too long....
