Depends on what bellhousing you have ? ,mine with a niteparts bellhousing is using the 4a fork with the w/series bearing/carrier with a spacer between them(NPC clutch).niteparts do a bearing carrier to suit (wish i had known when i got the bellhousing)
Apparently the toycoolrolla bellhousing from malaysia is supposed to use the w/series fork.
i think the dellow uses their own fork & bearing carrier.
What bearing do you have(is it 2 piece cast carrier with pressed on bearing or composite integral ?
