With some small machine screw and matching nuts I can sandwich the switch/s together... however... when the TWO switches (AC compressor and vacuum) are in their bracket locations under the center console they are actually stacked like two pancakes. With the machine screws and nuts I don't think I have the clearance needed, but I'll take out what's in the dash again to see if it'll work. (banging head against wall)I think their called button screws. Both the male and female look like a screw. The trick will be finding one the right diameter and length for your need. Have used them before a little blue lock tite and they hold quite well. What I’m really getting at is there has to be a fastener that will substitute for that plastic rivet. Don’t give up because you can’t get a direct replacement. Look around and find something that will work.
Hamerdown you might try a flathead stainless screw from RTL. They have them in small sizes. I have had success with something like this before, BUT, the countersink angle that has to be drilled in the plastic can cause cracking when tightening. Getting the correct countersink angle is important to prevent this. The most common countersink angle in US sizes is 82°, metric is 90°. There are many other angles but these are the most common. Do not use a drill bit to drill the countersink, it is the wrong angle and will cause the plastic to crack. The countersink bits are cheap and widely available. You have great tenacity, don't give up!Message sent, thanks for the idea/s.
