Ok an update from RM Performance.
Parts required are as follows:
3rd gear
3rd gear synchro
3rd gear hub
3rd gear sleeve
3rd gear selector fork
4th, 5th, 6th Baulk Carbon Baulk Rings
Competition Clutch Stage 3 clutch kit
Competition Clutch lightened flywheel
.....................
.....................
Now the unexpected parts:
4th gear
4th gear gear synchro
4th gear hub
4th gear sleeve
4th gear selector fork
Crankshaft rear oil seal minor leak
So although not knacked like 3rd gear was, 4th was showing heavy wear and so it makes sense to replace while in bits...
Plus side is my pink box clutch and lightened flywheel look in very good condition (only done around 4000 miles) so they will be sold on when I get them back.
Should collect in around 3-4wks as RM have a 2 week shut from Monday.
