What is the best method to install e body front and rear glass?
With the ribbon or some other adhesive?

There will be two sides of the fence on this one:
1. Old school, butyl tape.
2. New School, Urathane sealer and primers. My
vote is for New School!

And use rubber gloves.If you get the urethane on your hands and under your finger nails it's tough to get off.

I've a couple of these installs with AMD glass recently. Since the glass is thicker than the originals, I had to use 1/4" butyl tape to get the correct height. I backfill with a product designed for this called 3m glazing and bedding compound. Urethane is too rigid for this application.
