The cups are the bokt on type on the DZL box, so you can run 100mm or 108mm cups.. whichever match ur shafts.
The starter has 1 hole that needs drilling out iirc if u keep the vr6 one, otherwise the v5 will do fine but u need the bolt then as its threaded I think.. been a whike since doing mine, but its pretty much identical.. would reccomend a diesel 5th though..
