Long shot, but does anyone happen to know the thread pitch of the 10mm threaded bolts on the battery terminal. Working on an accessory and of course lost one to the engine bay.
To be honest, anything that fits through the hole will work. IIRC that is an M8 x 1.25 nut and bolt, however, the bolt has a special square head. You can probably pick up a set of M8 battery terminal bolts from the local auto parts store.
