Don't know if anyones interested, but was down the local scrappy the other day and there was a 480 in there with what on cursory inspection looked like a decent set of alloys on it. Had seats too though the runners appeared seized on the drivers seat. The place is called Kirby's and it's down Brickfields way in Rochford (near Southend Airport). Don't bother ringing them - its not that kinda place, just turn up wth a couple of big trolley jacks and a socket set (there's a car on top) and a pocket of readies (cash only!). Didn't ask for a price, but they tend to make it up on the day anyway. Hope thats of use to someone...
There's also what looks like a 360 for sale on the A127 outside central car sales (nr. Eastwood, just b4 southend) for £145.

440 seats dont fit in a 300 (runners are different width) - i presume 480s would be the same.. you could obviously bodge it if you wanted oto

Didn't think to measure, just thought someone might like the challenge. I've got to go back for some more bits soon so if they're still there i'll measure up for infor purposes.Don't see to many of them in scrappies, particularly this one, which is probably the cheapest scrappie i've ever been too!
