what in the heck kind of bolt holds the seat down??

Where would I find one of these things at?

Available from Mercedes if you want a matching one.

I just took my old one to a hardware store and asked for new bolts and washers all round.

I'm afraid I didn't ask what size it was so I can't pass the information on but they worked a treat.

I have taken them to different hardware stores but they aren’t common I guess or no one knows what they are doing

T1N or NCV3?

I've probably got my original NCV3 ones somewhere and they're in usable (but not pristine) condition. I just preferred to have something I could remove without special tools.

Can't guarantee it, (no idea where they are / might be) but if that's what you need and I can locate them then you're welcome to them for the cost of postage (from the UK)
