Gordo's DIY Dashboard Begins
I went to the local industrial metal supply place near me and picked up a sheet of 4'x4' perforated aluminum sheet metal, then I went to Home Depot and bought piano/strip/continuous hinges. This is the first step when making a custom dash. I use the strip hinges to make the various brackets that hold the dash to the car, support the dash top, and set the basic shape of the front of the dash. I cut the hinges into various lengths to suit my needs. Why strip hinges, you ask? Because strip hinges are like angle iron with an adjustable angle. The firewall, where the dash top meets it, changes angle in various places, the pivoting hinges let me fasten them in place regardless of whether the angle is 60*, 110*, 150*, etc. I use perforated aluminum because all the holes give me infinite ways and places to bolt stuff to it. You also don't want to make a dash that is rock hard out of beefy angle iron, this will kill you if you get into an accident. Dashboards are made sort of flimsy for this reason. My dashes, when complete, have roughly the same strength and collapsability as an oem dash.
I'm basically going to make a copy of the dash I made for my GTX car, but not so deluxe with gauges everywhere and no alligator skin. This dash will be covered in typical faux leather vinyl in a beige color.
GT dashes are almost exactly 48" wide and the overhang is almost dead straight to the tips of the arcs where the side vents are. This let's me easily line up the overhang edge with one straight side of the sheet metal and then I trace the windshield side of the dash onto the metal and cut it out with tin snips or other types of cutting methods. I make the dash go straight all the way across and eliminate the arcs and I don't indent the dash top where the urinal(glove box) is. I make a proper glove box with a door. My dash design is extremely versatile and you can easily remove individual panels to add gauges or features and leave the whole rest of the dash in place. I'll go into more detail later and I'll be making a video of all of this when I'm done. I use aftermarket everything for gauges, radio, vents, etc, When I'm done making this dash I'm going to try to make another one that uses the oem instrument panel and stuff and sell it to someone. I might make templates of the various panels so that others could make their own.
