'standardized' pcb tube socket?

I look for 7 pin and find mainly 15mm, 16mm pin circle products. I look for 9 pin and find 18mm pin circle products. That really messes up the pcb layout. Is there some international standard they are supposed to meet? It's too late now. I borrowed some layouts from kikad and a few other packages and settled on the 9 pin 21mm and 7 pin 18mm, neither of which I can seem to find. The boards are already being made. True, the 3mm difference is 'stretchable' if the socket pins are long enough but that wouldn't look so hot. Should I give in and just go with what the (mainly) chinese producers are creating 9 pin 18mm and 7 pin 15mm? That's another layout and board run.
