Doepfer

I'm building a little module to go along with the Doepfer ones in my rack here, and I'm desperately trying to find PCB straight mount 3.5mm jack sockets with a thread.  They seem common enough on modules, but utterly impossible to find.  

I want to mount the PCB parallel with the front panel, but 99% of the 3.5mm sockets on the market seem to demand a PCB perpendicular to the thing.  

Anyone any ideas? 

thanks, J.
