I am trying to get this car back to closer to original. For the 3 bolts that secure the tunnel console to the tunnel (the ones you see I mean), what are they supposed to be? I have a hard time seeing the shape in BAT photos. I only found 2 when reassembling my car. They have kind of a lip around them, but are flat (no shoulder). Seems an odd choice to use for the fiberglass tunnel, where the holes are kind of rounded (at least on mine, FWIW).

I have unrelated bolts I could use, but would like to use original hardware where possible.

Are you referring to the center console.

Two bolts at the back and a longer one in the change tray?

They are black oval headed screws...

Black oval head Phillips.

Thanks. I might have mixed up the bolts for this and the ones for the heater/radio console. Or not, haven't checked what those are supposed to be yet.

For any future lookers:
coin case: 08320-51242

The two in back: 08320-51242

so both locations are, according to this anyway, the same size. So I think that's M5 12mm length.

And washer-plain:

That washer at least appears to be available online.

The info in carpartsmanual.com for 240z... that's not like downloadable in any format is it? Would like to have it in the garage in book form.

Never seen washers on those console machine screws. Clearly there in the fiche aren’t they? Always thought the shape of the seat where the screw head sits were kinda tapered and fit the underside shape of the screws making washers an unexpected thing. Who knew?
