Diff ordered and on its way from Ipswich to South Wales, should arrive by midweek. Spent today cleaning and waxoiling everything in sight on the car, I`ve got friday afternoon and saturday to rebuild ready for SCH, fingers crossed.
I went to an open day at Prodrive yesterday. They did a demonstration of a WRC service and managed to change the gearbox and left (front AND rear) suspension in about 12 min's so you should be fine!!
Good luck with it mate, hope to see you on Sunday.
