Cheers chaps,
I might resort to eBay but I was hoping I could go to the local bolt supplier first.
Worst case I can always get domed nuts and washers.

Mate, i found the perfect thing for mine.
I work for vauxhall and have found that Vectra's btween about 03 reg and 09 reg have an unused earth point on the drivers side front suspension top with a domed nut on it. They are perfect for M20 rocker covers.
They're even colour coded with the car, ie i had to wait for 8 black sales vectras to cone thro to get them lol.
But if you want some unpainted you can order them from vauxhall.
If you want some i'll find out a price when i'm back to work

What you could do... Is... Drive to your local supplier, undo a bolt... Take it in, get them to match it... Go back out and refit the new or old one, depending on what your plans are while the bolts are off... I'm sure 1 bolt being undone wont affect to too much...?

Cheers mate, but I can't see them being any cheaper than the nut and bolt shop. No harm in getting a price thoughtomislav wrote:But if you want some unpainted you can order them from vauxhall.

Nice option but another to look into is removing the M6 studs and replacing with stainless pan head allen bolts. It looks sweet

You may well be right but i'll find out all the same. Being vauxhalls they should have a ready supply!!!!Touring Whore wrote:Cheers mate, but I can't see them being any cheaper than the nut and bolt shop.
