pin lock

Hello people of AHB, just been getting a keg set up together for a while slowly buying parts and i decided to go for stainless pin lock disconnects because I heard the plastic ones can break easily. Anyway the stainless pin lock fittings seem to be too big to fit on my keg? I was not aware of...

I've decided to convert my ball lock kegs back to pin locks (bought as converted pin locks). I've searched online and called Kegland and KK but no luck. Considering how many pin locks are converted to ball locks there's got to be someone with a box full of the things willing to sell some.
