Thanks for the offer, but yes, those are the mini contacts. I've got a
few of them and they just don't fit. I actually scored a box of the
right connectors on the auction site a few weeks ago. I've thought
about how to turn and support the contacts. I doubt that I'll go that
route because if I have to I can salvage spare contacts from the
existing boards. Each board has 16 contacts, but they don't use them
all. But I'd hate to do that.
