Exhaust Grille Questions, ‘84 308

The bottom part, which looks like the only part to be bent a little bolts up to the underside of the car so I think you're good.

Maybe a couple of the little vents are bent slightly but no biggie.

I would blast off the rust first (I did)

I re-painted mine with engine enamel and it's held up just fine.

 

Bolts, screws, washers for mounting?

Metric, assuredly; local hardware store is where i get small quantities of fasteners. Just need to figure out what size/thread pitch

Yep what Doug wrote, you should be able to see the screw holes (at least you can on mine) where they attach. I don't recall the exact sice, but I THINK they are M8.

 

depending on what plating and head you want on the bolt, if it is indeed 5mm x 14mm long, this will get you started:

Would only add to use stainless hardware if available. It won't rust (while not many of our cars get driven in the rain, most are still being washed with water I'd guess) and will resist tarnishing and oxidizing better than steel or galvanized. If you wanted to save some weight, you could go with titanium (kidding).

I would use round head/pan head. Allen. But that just me. Phillips can strip the X too easy and can't be tightened very well.McMaster-Carr PN 90909A725 or 97654A663 They come in packs of 10 or 25 Assuming an extra 2MM won't matter

Dunno what concours correct is
