Make sure you do/have done a SORN.
This might be really obvious, have you asked your local council about empty industrial units?
I found my old CarDisc International CD for Sprint GT/GTV the other day. Unfortunately it's so old it doesn't work on XP, Vista or Windows 7, but I can browse all individual scanned images on the disk. On it is a scan of an official Alfa racing parts catalogue. Once I work out the easiest way of extracting it from the disk as a set I'll send you a copy, it might give you a few ideas of what was available in the period, off the shelf.
