Anyone have a mid-80s Robinson-Nugent connector catalog?

Or some RN 68 pin CLCC sockets, or even a part number for them?
I tried buying a 1981 RFN catalog, but they weren't in there.

I have a bunch of IMS 80186 slave cards with the CPUs pulled
Of course, they didn't keep the caps. RN was bought by 3M and
I've been unable to even find a part number for these sockets.
I'm hoping not to have to replace the sockets to get these boards
working.

Pics of what I need are here
