Photo 4/21 | 1973 Chevy C10 Buildup OPP Solid Side Glass Kit | The OPP kit for the '73-'87 trucks comes with everything needed for the conversion, minus the tools. The main component is the new tempered and curved glass that replaces the vent window and factory side glass. The instructions that come with OPP's kit are thorough, so we'll just hit the highlights.
Photo 5/21 | 1973 Chevy C10 Buildup open Channel Area | The first step was to strip the doors of the vent window assembly and factory rubbers. In our case, the doors were new, so we just installed the regulators, handles, and locks. Ben started the install by opening up the channel area of the door where the vent window normally resides. This area is a little too narrow for the new felt to reside, but after opening it to about 1-inch wide the felt fit properly.
Photo 6/21 | 1973 Chevy C10 Buildup weatherstrip Adhesive | The new outside scraper was adhered to the door with weatherstrip adhesive. Ben said he is working on a new design that will have the factory-style clips so you can just snap it into place. Until he comes out with that, the weatherstrip adhesive will do just fine (he's just trying to simplify his kit). Not photographed but important, was the cutting of the support strap that tied the inner and outer skin of the door. This is right below where the vent window would be and was cut with a hacksaw, again the instructions will show exactly what we are talking about.
Photo 7/21 | 1973 Chevy C10 Buildup 4 Inch Extension | Obviously the one-piece glass will be much larger than the factory glass, so the channels needed to be either replaced or moved. The factory rear channel was moved back with this 4-inch extension piece and was bolted in place in the factory holes.
Photo 8/21 | 1973 Chevy C10 Buildup roller Channel | A new roller channel was provided in the kit, which was used to connect the glass to the regulator. The factory channel was permanently fixed to the glass, where this one is redesigned to be bolted to the new glass, which makes it easier to install.
Photo 9/21 | 1973 Chevy C10 Buildup one Piece Tempered Glass | Now the new one-piece tempered glass was fed into the opening. Ben has been doing this for years and made it look easy. We later found out, when we removed them for paint, that the glass is pretty simple to install thanks to the redesigned roller channel.
Photo 10/21 | 1973 Chevy C10 Buildup glass Bolted | Here is where the glass and the roller channel were bolted together with the provided hardware.
Photo 11/21 | 1973 Chevy C10 Buildup front Main Guide | A new front main guide was provided in the kit...
Photo 12/21 | 1973 Chevy C10 Buildup extra Drilled Hole | ...and used one lower factory hole along with a new hole that Ben drillled to mount to the door.
Photo 13/21 | 1973 Chevy C10 Buildup OPP Template | OPP provides this template in the instructions...
Photo 14/21 | 1973 Chevy C10 Buildup new Drilled Hole | ...so there was no guessing where to drill the new hole.
Photo 15/21 | 1973 Chevy C10 Buildup urethane Strips Glued | The area right where the doorframe and door skin merge was a little too deep for the channel felt, so a few small strips of urethane were glued in to hold the felt out.
Photo 16/21 | 1973 Chevy C10 Buildup felt Tucked | Once the felt was tucked in place, the install was almost done.
Photo 17/21 | 1973 Chevy C10 Buildup door Measurements | A few little things needed to be addressed before the window could be rolled up safely.
Photo 18/21 | 1973 Chevy C10 Buildup electric Door Lock Solenoid Lowered | The electric door lock solenoid needed to be lowered about 9 inches to the bottom portion of the door.
Photo 19/21 | 1973 Chevy C10 Buildup connecting Rod | A new connecting rod was made from a piece of stiff rod and a few bends with a pair of pliers.
Photo 20/21 | 1973 Chevy C10 Buildup lock Cylinder Arm Trimmed | The last little mod was trimming a 1/2-inch from the lock cylinder arm. It will still function properly once trimmed, but it won't scratch the new glass. By moving the rear channel forward, the stock door lock tumbler now interferes with the windows roll down path.
Photo 21/21 | 1973 Chevy C10 Buildup windshield Installed | Because we were at a professional glass shop and we had a long journey ahead of us, Mike decided to have Ben's crew install a new windshield (because the old one had a massive crack in it). Now all of the glass was new except for the rear window, but that is covered in purple tint and will work for now.
