Inner fender to steel fender fasteners

[Rt Jam]

Just putting my car back together. 87 GN.
What size are the bolts to fasten the plastic inner fenders to the fenders.

I had 16 M8, 10mm head, set aside for this but the driver's side front most 2 bolts have a M10 nut in the hole. I have a spare fender and it also is M10?

My battery is on the passenger side.

Hmmm. I was always under the impression those were M6 x 1 x 25 captured washer bolts with 10mm head sizes. M8's usually have a 13mm head. An M10 nut seems a bit huge for this kind of application.

My memory is foggy here as it's been a while since I've goofed around with the liners. The parts information is useless in this area by not calling out any fastener information in this area. Well, more like I'm useless in not being able to locate it.

I just installed the left inner in my Malibu coupe yesterday. Youre correct on the sizes. Not sure if a GN would be the same but Im thinking they probably are.

Yep, m6 and I changed the 2 speed nuts to also be M6. Now the plastic inner to steel inner are all matching. Thanks.
