I think the ones at the front might be M6 x 62 with the part number 77 00 106 428

and the left ones might be 77 00 106 429

Thank you guys. The part numbers @JamesBryan put up seem to be the right ones. I'm going to buy one of each to establish the pitch and then buy stainless equivalents .

Careful with stainless steel. They don’t rust but any other metal in contact, particularly aluminium, will corrode extremely quickly. As in days and weeks.

It’s a big problem with sailing boats, stainless steel fittings on aluminium spars.

Stainless often has less tensile strength than steel and it can work harden.

True. Just reminds me of the Brembo caliper Pins that get seized. Total nightmare

Galvanic corrosion yeah.

I was planning on yellow zinc plating them , do you think this will help ?

Or am I best off buying Renault bolts and yellow zincing them?

Plating them is fine mate, but in my experience the plating process that the manafactors use seems to be more robust.

Maybe worth pricing up a new set from Renault unless you did want them yellow?
