Nahhh, don't be daft, Ian, no reason anyone would suggest you should have been aware of it. After all, who'd expect a bumper to be two inches wider than the car

It's just sod's law and about the way my luck runs is all
It's very odd, though. Like I said, we're not talking about fibreglass that's warped a bit from being stored at a funny angle or a bit bent in where the car's had a knock or whatever, we're talking about it having been deliberately modified to... errr, not fit

You'd only really notice the fibreglassing alterations if you were looking for them, cos age and grime hides them and you have to look at the inside anyway. Once you know it's there it's clear where the fibreglass matting used is different to the original and such like.
The solution J came up with is a bit drastic but basically it involves cutting the trailing edge off where it lips around into the wheelarch, putting in a fillet of about an inch and then glass it all back together. It'd be easier just to lose the lip entirely and thus slide the whole bumper forwards, but we decided to fasten into the wheelarch rather than the face of the wing like it did originally for the neatness of it, so this is the only way. It's all bolted up to the frame, too, none of that weird No More Nails mastic stuff that glued it on originally, cos ...well, gluing your bumper cover on is a bit of a pikey way to do it and makes it really hard to ever get it off again.
It's a lot more work than we expected, but it'll be well worth it in the long run. On the upside, I've got a spare switch in the console where the aerial errm, isn't, so it'll be easy to wire up the fogs
