Hi all, i have a mk3 astra gsi with c25xe engine fitted, the f25 box has finally given up, so i'm gonna either put a f20 or 1.7td cav box in, what items do i need to do the conversion?

Flat type xe flywheel?

Gearbox (obviously)

new clutch?

Will i have top use the v6 driveshafts or v6 shafts?

What kind of spacer would i need?

Anyone know of a conversion guide on here i could follow?

Help needed urgently!!

Many thanks,
