i know that this topic has been discussed several times on the site but I thought my experience may aid any members who are contemplating this fabrication.
Disclaimer: No animals were abused except me during this production!
What is needed-Almost everything was purchased at Lowes but unfortunately not at one time. Cost about $100. 1. 1/4 inch clear plexiglass 2. 1/4 inch wide U shaped aluminum strip 3. 1 inch wide aluminum strip. Long and medium aluminum pop rivets 4.clear silicone sealer 5. household door weather striping bonded to aluminum strip. Hacksaw and jig saw blades.
Tools necessary: Drill press (optional), 3/8 in. elec. drill, hand held elect. jigsaw, hacksaw bench vise, assorted drill bits, pop rivet gun, masking tape, ruler, marking pencil, grinder to grind and polish (I used a die grinder) and various hand tools.
On one side I welded ( really soldered or brazed) aluminum pegs to the 1 in. aluminum strip to fit in the top of the door-don't use map gas-its too hot-I used propane. I then positioned the 1/4 wide strip to the strip outward of the door top over the door skin to block water entry and pop riveted them together.
I then made a pattern for the window out of 1/4 inch masonite and set it in the 1/4 in. channel to refine it. I clamped the pattern to the plexiglass with a 3/4 in. plywood backer board and used it as a guide to cut the plexiglass. The plex. will adhere to itself from the heat of the jigsaw blade but I eliminated that by placing masking tape on both sides of the cut. I placed silicone sealer in the U channel and set the plexiglas in there . To finish off the job I pop riveted the weatherstripping to the outside of the channel to give a nice finish and to waterproof the window to door junction. On the other (passenger side) rather than "weld" I made U shaped brackets with wings to hold bolts that fit into the door holes. I finished the job with strips that snap into the inside of the doors like the original curtains. I glued weatherstripping ( from a 1968 Camero that I had restored ) to the inside of the windshield frame to get an almost seal. I discovered that by rounding and polishing the plexiglass edge the door closes easier and the window fits under the canvous flap on the top better. The car looks much better now and the visability is improved. Pictures to follow.
I hope this inspires anyone-Joel
