I made a template out of a couple of manila file folders and then placed it on the the repro dropoff and marked off for cutting. I used a plasma cutter (a really fun tool) and trimmed it down to size until the panel just popped in exactly. These repros fit very well, right out of the box when it comes to aligning with the edges of the GM quarter.
Here's the repro panel being trial fit:
The adhesive it premixed in the funnel that attaches to the dual cannister and is first applied to the mounting areas and brushed over any bare metal area, as well as any area that is to be a bonding point. Then a liberal amount is squeezed out onto the panel and the panel is put into place. A bunch of vise grips are then used to clamp it in place, but not too tight. You dont want to squeeze out all the adhesive.
Yeah, I know that's sacriligious to use that clamp on the paint...but the paint is old and bad and I have a piece of cloth under it. This was the only way to get the upper portion held in place. The clamp is pressing on a section of wood across the upper bonding seam. Plus, they are my Grandfather's woodworking clamps from three quarters of a century, ago.
