Trying to source a couple of bolts which fix the knuckle hub to the front shock absorber strut.

Part number 1309104080

My googling is letting me down. No obvious joy on Ebay or Amazon, either.

Does anyone know whether I can just use a regular nut and bolt here or is it high tensile like the Pinch bolt in the wishbone ball joint.

Or, is there an equivalent part number for citroen peugot? Is there an equivalent to eper for them?

Answering part of my own question - got access to Citroen Parts Catalogue

http://service.citroen.com

The nut and bolt are Citroen Part Numbers 6936 65 (nut) and

5223 09 (bolt)

Have a look at the head of the bolt. Standard bolts are usually 8.8 grade, but some suspension bolts are 10.9. If 10.9, this should be cast or stamped onto the head. The nut needs to be the same grade.
Don't be tempted to go stainless unless they are 8.8, as the best stainless are only equivalent to 8.8. See the Westfield info section for details.

Once identified, measure it carefully and browse these sites.

I've used all three of the above, with good service from all.
