commo mounting rack for pickup

[GerWJ]

morning group...... I got one of the racks that went in the back of M37's, M715 and M880's to mount radios and other com gear.... would mount about 12 pieces of gear.... I had one in M37 with a RATT rig , had neat old angry 19 radio, fun radio to set up and get going, but once going could talk and send all over world...... anyway in the back of the rack is a pwr distribution box.... got all but the main pwr cable that feeds it from batteries..... if someone has a cable they want to part with or at if you could post the part number so I can look for one..... haven't had much luck locating one.... much easier with good part number
want to mount in another vehicle
thanks for any help or leads
