So, getting back to the narrative....

The roadster panels will be covered in medium brown 'pleather'. I recently thought about hiding 4 two inch analog gauges in the center arm rest. The reasoning is that the Audi gauge package is 'pulse' operated and controlled by computers. They are notorious for being difficult to keep operating right. I don't want the hassles so analog gauges and a GPS speedo seem the way to go.
The front bumper was another issue that required some thought. I wanted it to look differently and using the Charger grill means the turn signals are up on either end of the grill and no longer in the bumper. THOSE had to be shaved. OR, a different bumper. I also didn't like the Charger bumper shape. Since i changed the fender noses the bumper ends stood out from them like 5 inches. No Go. So, I sectioned the bumper into three pieces. I cut out the two curves which rotated the ends back towards the fender reveals. A few adjustments and shaved signal holes later and Bob's yer Uncle. I took the grinder to the rear edge of each end and trimmed carefully so they matched the fender reveal outlines perfectly. All of the parts formerly on the firewall are now under the dash.
The spare tire resides in the center of where the rear seat used to be. Sold that too. battery is in a racing box behind the passenger front bucket.
That leaves the big mod to talk about.
1966 Thunder Bird tail lights.
To begin with, I thought about 67 Charger tail lights. Too short, left to right. Then considered several other cars, discarding all.
While prowling around a new, to me, salvage yard with my pal Rick one afternoon we came upon a 1966 T Bird. I stood there, he stood there, and stared at the ass end. We looked at each other and said, at the same time, " I wonder how wide that bastard is?" lol! Great minds.
I pulled put the tape and low and behold. It would fit with minor shaping of the quarter extensions. PLUS, it the blink, blink, blink type of sequential lights when using the turn signals. The back up light is in the center of the light panel, good because I lost my back ups when I changed the bumper and opted for exhaust coming out of those holes!
Match made in heaven.
The sequential controller was intact and like new still inside the fibrous pocket they come in to keep them clean and dry. I pulled the out bezel trim too. I needed the trim around the outside to go all of the way across the light bar but the 66 stock trim is not like that. So I ended up buying two more trim pieces and cutting them to get straight pieces to enclose the whole bar.
Now the fun part;
Figuring out how to completely redesign the rear face of the car.
A 67 Coronet has the trunk lid flowing down vertically to the top of the rear bumper. I now needed it to stop just over the brink of the slope downwards. That means I needed the trunk seal rail to be at that level too, and not down next to the bumper. The lock/latch needed to be up there. I was constrained by the shape of the quarter extension tail light cutouts as to height position from either top or bottom. This took a lot of thought and several tries.
Not to mention slicing the vertical face of the trunk lid completely off. Then having to create from nothing the entire bottom side of the trunk lid end to match the trunk seal rail I just moved up. Did I mention I have moderately severe TBI brain damage? Complex stuff eludes me. I cannot remember complex operations long enough to complete them? Yeah...so there is that.
It was a fun thing to complete and it took me two years. JUST THAT ONE THING. Two. Years. But it's done and it works. lol.
Next there had to be a close out panel behind the light panel inside the trunk for appearance. That took a lot of trial and error. I decided to install close out panels with material on them, just like in a newer car trunk. As if this was not hard enough i kept adding to it.
Rick told me one day, to stop adding stuff. lol.
So after all of that time the bumper, trunk, lights and quarter extensions all work together. yes.
