For most of the threaded pieces for the various projects that I have underway, I use Boltbase
Single, multiple or bulk and very fast delivery: http://stores.ebay.co.uk/boltbase/

Mine mostly fell off the other day. I managed to get one screw to hold it up and limped home.
Armed with pack of cable ties this afternoon.
I considered one of those metal undertrays for the Spider which is not as bad but the thing is the threads and holes seem to get quite rusty.

I had not yet looked to see where the jolly oil filter is sitting. Can that only be reached from below by removing the tray then?
I use one of those gizmos to drain the oil, it's a very efficient process, no grovelling about.

My Brera's undertray was removed a few weeks back by my local Alfa garage. Bloody thing scraped on every little bump around after it was lowered slightly. Plenty of room between the undertray and the engine so it's not that dangerous. Cars never used to have the things until a few years ago anyway.

If you do remove the undertray bear in mind it attaches to the front lower valance.
That can then flap around to some extent - easy to make some alloy brackets to remedy it.

Mine I believe is fastened up better than ever but when I go over those pillow type ramps it catches. Might just be a cable clip 'tail'.
I was in Lincolnshire over the weekend on some decent roads. If the road is a bit bouncy I've noticed and occasional touching of the road below
