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

[n86121]

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.
