[WIZ96]

Does anyone know if a adpter plate for crossmember for manual conversion have to be certified in nz?

Turns out this is a good question. My understanding is that if it can be bolted its ok but not welded. However a wof issuing mechanic on here has a differing view. Also consider the driveshafts as they need changing. If Mu or bighorn then manual ones exist but with a wizard you need to modify the rear driveshaft and that does need cert.
Best to talk to a certifier before you start
