Need help finding long shaft potentiometers for active preamp

Hi guys I have a 90s Cort Artisan bass was a bit abused and needs new pots.
I'm having a hard time finding the right size since it's a Hazlab style pre and the threaded shaft needs to go through the body. On the original broken pots the threaded section is 16mm (about 0.6 inches) and the shaft where the knob goes is 10mm (0.39 in.) so a total 26mm. They are also mini pots with pcb terminals but I think bigger ones would also fit and I can adapt the lugs.

They are two B100k with center detent, one B500k and one blend pot stamped A25k/C25k with center detent.

I live in Italy and have searched Mouser, RS components, ebay, amazon and haven't found much. I think Bourns makes 25mm pots with long thread, can I order directly from them? Any suggestion would be appreciated thanks!

 

Yes I've sent a message yesterday, waiting for an answer. Thanks
