A very clean BNC jumper to replace the missing ones on the rear of HP equipment can be had by purchasing a couple of Amphenol 112614 right angle BNC connectors and a short length of RG-405/U semi-rigid coaxial cable.? The former can be purchased from several vendors and the latter from your favorite auction site.? Assembly is very simple requiring a couple of strips to the cable and soldering the shield and center conductor to the connector.? The cable has Teflon insulation so soldering of this small cable is a cinch without melting anything.
The BNC connectors have a threaded cover to access the center pin making assembly a cinch.
