I discovered something about the temperature control doors for the heater boxes today.
There is the inward facing swing arm like this:

Then there is the outward facing swing arm, like this:

Mine is like the second one but when I got it the swing arm was broken off.
After searching far and wide I found a guy that had a temperature control door and bought it. It was when I went to install it that I discovered the arm was in the wrong position.
I looked at the rod and it was only welded to the door in three places, so I thought grind the welds, rotate the rod and reweld it in the correct position.
This is when the other difference between the doors became obvious. The arm that points outward is 5/8" longer than the inward pointing arm.
So I took the old broken rod and put a bend in it (Yes, I know it's not the exact same radius) and then cut to the correct length and weld them together.

Beveled the edges and MIG welded them together. The slot is for a retaining clip.

Positioned it and welded the door on:

Dressed the welds and painted it.

Applied the foam and installed it:

I need to replace those rivets as they aren't tight enough. Just aluminum rivets that I put a washer on the inside hoping they would secure it but definitely not good enough. The gasket/foam package I used suggested split tail rivets or something like that. Never heard of them before.
Well that snowballed!
