[Boatanchors] Looking for Collins Part...

[radio_man at wbsnet.org]

Just finishing up refurbishing a KWM-2A & PM-2 for a customer now need
some small parts.  Am looking to buy or get information where to buy -2-
Collins P/N 545-7688-002, as spelled out in PM-2 manual.  They are
described as a 'chassis nut'.  Is an adapter that is 3/8"-32 SAE external
and 1/4"-20 internal.  Is for mounting the PM-2 slides to the KWM-2.  I
can come up with the nuts and washers but have not found the chassis
mounts.  Could also use some thumb screws, P/N 545-7702-002.

Any suggestions or leads?  No luck on searches.

Thanks
Rod
