[quote="Dragonlord":1hr9uamk]Sheldon, once you get some rest from NAMM and if you have some time and that info handy, please please answer these questions in my last two posts, as I'm talking with Udo and he's waiting for my reply to see if I can place an order.
To sum the questions up:
1) Won't I be able to use washers to install a glock preamp on my 10-year old prima with larger holes? Would you recommend against it for some reason?[/quote:1hr9uamk]
We've done this in the past and had a problem with the pot tipping over and shorting on the shielding foil. Washers hold OK for a while, but when they loosen, then the problems start.

2) Do you remember the diameter of the bartolini pots?[/quote:1hr9uamk]
9 mm.

3) How thick is the surface, where you mount the pots and which diameter do your actual pots have?[/quote:1hr9uamk]
3.75 mm +/- some sanding and finishing differences.
You may be in luck. I have 5 custom nuts left in stock that we made for such a purpose. Keep in mind, nuts made by the thousands cost pennies each. Custom nuts made in small batches are expensive. I'll have to calculate a cost on them, but they are likely $20 each.
They thread onto a Glock sized pot, fit the hole for the Bartolini properly and prevent the pot from tipping.
