After spraying yesterday the paint had gone enough to handle them and was very exciting to fit them. New stainless fixings have been used all round and new galvanised mud shields have also been fitted. Everything was first tightened up finger tight then screwed down once everything lined up.
Amazingly, almost everything lined up perfectly. The passenger side mud shield needed a little attention from the angle grinder to make it fit though. Other than that, things went well.
Whist I was there, the front valance was also fitted. I needed to drill and tap a couple of holes in the top of the chassis rail to hold the front section. I assume a self tapper would have been used originally. I only have ugly self tappers from the local hardware store and I think a couple of imperial stainless bolts look the ticket.
