Well I got them in and no more wind noise from them.
Old versus New. As you can see the old one has a nice gap where the window was for 20 years.
The first step is to remove the door panel which isn't too bad, but I have done it a few times already.
Here are the 3 phillips head screws that attach the mirror. They can be a real pain to remove since toyota used thread lock. I only had to drill one out since the head became too stripped. I replaced them with nice allen head screws. And i didn't take a picture of it but there is a small screw that hold the door gasket that will also need to be taken out.
Here are the two bolts that hold the top of the support, but the mirror must be removed first to get to them.
And finally remove this nut on the inside of the door that holds the bottom of the support.
In the end I think it was worth it. I don't think any fix to the old seal is near as good as a brand new seal.
