have just swaped my crap serveta 150 box for a sil gp200. will i need to change my clutch spider or will i be able to re use the one i have, and do i need to swap anything else while im at it. thanks

all stays the same, just shim the new box correctly

cheers, my mate is building it for me, not done a gear box before! but he was worried the preasure plate/flange would not mach up,have read that i need to swap the needle bearing that i have, for the brass bush type as the sill christmas tree wont run well in it?

I think your getting confused with the needle roller bearing for the clutch bell, the GP clutch bell uses a solid bearing whereas the SX/LI clutch bell uses needle rollers, the gear cluster/Xmas tree, GP or SX/LI always runs in a needle roller bearing
