Good experienced advice..... I did the rear window (small) quite easily with a helper but it was a much different installation. The Factory manual shows the windshield seal/gasket, I assume with the larger "extra" flap of rubber on the up side inside. right? Also the manual shows trim clips slid into the reveal molding on the bottom piece of the four only. Is that correct? Trim clips on the lower stainless piece of trim? If it all goes in as a unit, I can't see that working out. Am I misssing something here for this 59 Apache...... Ralph
