I have replied to those who have sent PMs.

Fuel rail may be reserved by a friend and same applies to the rear brakes. Also have someone lined up for the front diff, oil cooler and wiring harness.

If not they don't want them then...

Front diff - £1200
WRC 909 air to airs - £300
Rear brakes - £200
FPR (-6 fittings) - £120
Fuel rail (-6 fittings) - £100
Aeroquipped fuel lines (-6 fittings) - £200
