Turns out it was just as well I checked the front end, as I hadn't spotted how bad a splash panel and the wishbone mounts are.
I knew the rear mount was bashed about, as I'd done that getting the old wishbone out. But I hadn't realised that the front mount was about to part company with the chassis rail. The splash panel is nothing to worry about, as it doesn't do much. So I cut the folded over bit off, and hammered the rest flat. I'll tidy the edge up a bit more another day.
Since the front mount is so bad, I've started to cut the entire thing off outboard of the chassis rail. The inboard bit will stay and form the basis of a new mount. Both mounts were always destined to be cut about, but I hadn't intended doing anything more than making room for the new mounts. Whilst this is more work, it's probably going to give me stronger mounts at the end of it all.
