Specific steps to replace (outer) side windows - de-rivet?

[B2C2]

i looked through this, but cant completely figure out the answer to my questions from the posting. Is it possible, on the 1969 T model, to remove and replace the inner windows and seals without drilling out external rivets? If it is where do people suggest getting the replacement inner windows and seals?

You should be able to remove the inner window with just one small piece removed by drilling out rivets and this may not be on all windows. The rubber seal is placed around the plate window and then the window is held in place by the channel and the seal is pushed against the outer plate window. Should be pretty easy to do. The new inner window with the seal around it fits in place where the old one comes out. There may be one riveted plate that might have to be removed on some inner glass but that is really easy to drill out the rivets and then just pull new ones in. You should only need to remove one piece off one side and pull the glass up out of the channel.

Basically just remove only what is necessary to remove the old window and then put the new plate in with new seal just like you removed the old plate

The first photo shows the finish with the new inner glass in place with the rubber seal and window in fixed channel
The second photo shows the inner glass out and the channel that secure it in place
The third photo shows everything out including a small plate that is riveted

thanks for the clarification. Where did you source the seals and the new windows?

In may 1969 T337D, you

1. Pull out the side trim pieces, and
2. The INNER windows just have rubber seals around them*.
3. The seals just sit in simple press-in frames.

No riveting, no hassles.

For turbo/double windows you want the window rubber gasket to be non-symmetric, to maximize the distance between inner and outer window. Otherwise with vibration they will rub / haze at point of contact.

awesome thanks for the help. I have a 1969 T337D so that's perfect. I am going in for annual in two weeks, assuming no major issues, I will tackle this as a "while you're at it".

With this annual, I've pretty much decided to go with clear OUTER windows.

Just need to confirm same as front and door as already as done more recently.

Reasons are:

0. BY generally parking facing north, angle of incidence on windshield is better than tint!

1. While 'smoked' might look cool, loss of light & contrast at night and IFR

2. Except for pilot side and door, other windows are under wing and shielded from sun.

3. Inner windows are easy to pop in/out in just a few mins.

3a. Inner windows under wing may be just fine. We will see.

3b. Easy to redo INNER windows later on

3c. Inner windows non-structural, so can buy any old UV plastic anywhere: $25 for fancy UV + tint vs $200 per window

3d. Can change INNER to tint or clear easily and inexpensively as desired at any point

All original side windows from 1969.

Windshield was replaced to match,. circa 1989. It's still fine. Tied down facing NORTH.

Originals were apparently green tint....

...So I guess I will be going green tint!
