I am trying to re-install the entire wiper door mechanism in my '72. Does anyone know where I can get information on where to start concerning the use of shims on the mounting points and where to get said shims? I have the AIM but it just says shims as required. How to adjust the initial position for the mechanism also would help.
I am at the point of just abandoning the entire wiper system and putting in a block off panel or solid mounting the original panel and grill. Hey its SoCal and it never rains here and who would drive 550HP in the rain anyway.

 

OK I'll give it a try
When I installed mine (memory isn't what it used to be)
<<< STUFF RAGS OR TOWEL IN THE SIDE BOTTOMLESS PIT SO YOU DON"T HAVE TO REMOVE THE KICK PANELS TO RETRIEVE EVERYTHING THAT GETS SUCKED DOWN THERE >>>

Install the grill between the door and the hood and slide it all the way towards the front of the car so it's not in the way of the door

I bolted the hinges it with no shims (not even the ones I removed) and closed the door (without the actuator), set the height of the fixed grill as close as you can sliding the hinges up/down in the slots on the firewall
Looked front/back on the door edge and compared to the fender and figured about how much back it needed to go to line up, that gave me a pretty close guess on the shim thickness I needed to use to space the hinge mechanism back towards the windshield

Installed the shims (they are just flat metal plates with two holes, I used most of the stock ones but left one out. I think you can order them through CC or whoever but they are all the same thickness
They are a pain to install and slide in, I taped them to the hinge after dropping them several times as I recall.
There is a screw that goes against the plastic pad on the car to help fine-tune the height when closed, this also has a slight affect on the front/rear location but not much at all
Snug everything up and double check

I needed to add a couple of shims under a few of the screws on the fixed grill to get it to fully match the hood/fender/wiper door but that wasn't part of the factory stuff

Anyway, hope it helps

Thanks Mooser, it's a start. I just hate installing and removing the entire mechanism over and over risking paint damage each time.

 

Lots of blue painters tape
