Paul the spacer is on its way,  UPS to you on Monday Tracking number 1Z950X280355911411  T.W.

Thanks Tom.
Here are what the 3/8th buttons look like.
A 1/4 inch button that I made is also in the picture.
I am much much happier with these. A much, much more robust
connection with the Teflon slide.

Two 3/8 th buttons are in the mail to you.
