Some miscellaneous spares I found in a bin:
1) 14CUX ECU - I bought it tested and used. Never installed in my 90. $60 shipped.
2) MUD UK seat risers - The thumb screws and levers have seen some wear. The lever action allows you to still remove the seat easily. $50 shipped.
3) Seat risers - not sure where this are from RN maybe? They bolt down, so access to the underseat storage requires removal of bolts. $50 shipped.
Everything is OBO. Attached are some quick and sad pictures.
PM me with questions.
