I never purchase important items from fleecebay, sorta like throwing the dice, you might get lucky, but more than likely you are gonna loose out.
TT and LowRange sell bearing and synchro kits for the track/kick's.
As for the clutch disc I would opt for a close to OEM clutch, dont fall into the trap of performance parts being better.
Stick with someplace reputable rather than some pajama wearing skeezebag reselling cheap crap on fleecebay.
