wat sort of mods have to be done to fit it in wat engine mounts would i need and if any one can tell me if it can be rego in nsw and how much will it cost for a mechanical cert and wat diff would be ideal

u can use engine mounts out of xa xb xc xd v8 these are all the same and will bolt up straight on front cross member when u remove 6 cylinder pedestalls . If using c4 tranz this should bolt straight up to gear box mounts no modifications . is vehicle going to be manual or auto
