The Radio Information Board

Does anyone know where I could get something to use as a jumper to keep the model 5300 Logic Board connected to the rest of the radio while I troubleshoot the bottom of the board? There used to be something like this for Bendix/King portables. I will probably have to make what I need -does anyone have an idea as to where I might be able to get the connector and header or any 5300/5100 parts for that matter?

They sell a jumper cable for the 5100s I know. I don't recall seeing it for the 5300s though.
