Duh. Dont think i didnt spend 30 minutes down at Enza Mercedes looking through all the bolts they have to find a similar pitch and thread length. Couldnt find anything!
As for Shims, i should be sorted but Toyota have let me down and got me all but 1 shim.. I still need a 3.2mm one, but that should be here today.. And it should of been here yesterday.. And it should of been here the day before that.. etc
Paz, got loads of exhaust manifold studs, and i'll have a look for the shim that you need. Im at donnington next week so i could meet you or post them dude.
