Who made them? I learned a couple of years ago when they were hard to come by there were at least two different manufacturers. Each had their own valve stem threads. I needed those previously made by A&L. The ones I initially ordered were not and would not work on my stems. I don’t remember who made them but, if you can use these, they are available.[/QUOTE
If you have 5 that are the same and they are right for 31, I'll buy them from.you. I don't have my stems yet still waiting for delivery. Snyder has them, as well as Mike's, but all are "temporarily" out of stock.
