About to start repairing a second 5065A. Gathering parts.

Looking for a replacement for the still available but very expenceive OPA111 used in later versions A9 Integrator of the HP5065A.
There are indeed some candidates at Digi-Key, but when the selection of max Input current, offset voltage and supply voltage is set, there are not that many left. So - which parameters are the most crucial for the integrator?

Looking for data on the Ferrite bead HP 9170-0029. Any suggestion on a suitable equivalent?
Looking for the teflon single pin feed-thru connectors used on almost all modules on the 5065.
Best Regards
