I just got done putting the quarter window metal framing in my coupe. Not permanent, just to drill what holes I need, and see where to weld. I took these out of some quarter panels, I removed from the same sub-frame. I bought the quarters & cowl assembly, they were all that were left on a rusty sub-frame, with a rusted out rear panel. I was looking at the garnish mounting, that the trim screws to. To my surprise, they are two totally different types of mounts! I don't understand why they would be that different, on the same car.
Like someone told me on here before, surprise, surprise, golly! (Gomer Pyle voice)
This is the passengers side, it has clinch nuts, that stand up at a angle, tilted in ward.
This is the drivers side, with nuts mounted under the framing. that lay flat to the surface.
Although they look the same from 25 feet (assembled), there were many changes in the 26-27 bodies. One big change was floor pans. It wouldn't surprise me if anything else was different.
I understand that there is differences, I have been dealing with many of them, but the left & right side of a signal car being different. Not two different cars
Pat, I think my qtr window garnish moldings are different left to right. The mounting locations in the body were the same for both sides, but the moldings came from another body. The molding on the left side fit fine, but the one on the right window had gap of 3/8" at the top. The front fit good but there was a tapered gap that I filled with hard rubber chunk shaved to a taper from 3/8" to 1/16" from top to the bottom on the aft mounting area. The shim is between the glass & molding. I goofed by not checking the fit before final assy, so it was time to make sh&T fit !!! It won't be noticed by most.
Here is a couple of pics:
