OK, a little behind schedule but finally got the prototypes in ABS in my hands to check out. I didn't go through the whole process of bolting it on my car since it is the same as the PLA one I already tried. However, I have spare set of sport mirrors I checked them against the bottom and checked the holes in the driver's door for fit. Here's the latest pictures of the ABS units. To be sure, these are just wedge gaskets, no lip around them, no locating tab. This is pretty much what you are going to be getting as the final product. I would not call them show car quality and they are not rubbery. They are functional and set the mirror at the proper angle. Tomorrow I'll get recommendations for best way to ship them and figure out what that costs and start down my list.
