286 to 386 processor upgrades (and the amiga bridgeboard)

I just bought a 286 bridge board for the amiga. Much fun awaits... Does anyone know of a stash of 286 to 386 processor upgrades anywhere? I seem to remember a few companies marketing these. Also, iirc, there's a daughter card on the bridge board that covers the 286 socket. Any idea what I can use to widen the gap between the daughter (sandwich) card and the bridge board so that the processor upgrade would fit? Some short ribbon cables might be all it takes. I have an ide caching controller, scsi controller, sound blaster board, and network board ready to plug in. Still need a vga board. I have a 5.25" floppy floating around somewhere, but i'd like to find one of those 5.25" and 3.5" floppy combo drives. Imagine the possibilities :-) What I'd really like to find is one of those isa bus extenders that plug into a passive back plane in another case. With the external scsi tower, that would go a long way toward turning my 2000 into amigazilla. :-) brian
