My C5 was originally equipped with a dual-battery setup, but all the parts have been removed in the past. I'm looking to put it back to original, so am looking for the following parts:
Keyswitch assembly and wiring (most important!)
Battery securing strap body bracketry (not fussed about the buckle or webbing as I need to make a new one up anyway)
Battery "foot" that bolts in the rear in the footwell
Battery lid
Battery terminal cover
Battery strap
Phew!
Photos of the parts..
