Cgs synth

Hi all,

My first post here - forgive me if this question's been asked before. I searched the archives
but didn't uncover anything that answered it.

I'm placing an order on Allied for parts for a CGS60 and I can't seem to locate the 6.3mm
sockets anywhere. Is there another term I should use that will bring them up?

I find it hard to believe they simply don't sell them....

thanks,
Matthew
