I just saw your comment...My first thought was to say no, but I just looked and I have enough to make just one more set. I believe it is the high impact acrylic but don't hold me to that.
I would need to buy the clamps I was using...drill and prep them for the set screws. It looks like they are still available online with a few days to get them.
I believe I was charging $145 including the shipping to the lower 48 states. It's been so long I can't remember. I made and sold a lot of them...they do help. What is you pleasure as it would be about week before I could make and ship them.
