looking at putting a Monaro cv8 diff centre with cv joints 3.46 ratio LSD into my vz calais v6 , for better rear wheel action . is this a bolt on no troubles ?
Yes it should be just bolt in, just check that the 3 bolt flanges are the same size as series 2 (no such thing really) VZ's used a larger 3 bolt flange but may only be on the 6.0L V8 versions.
