Just wanting to know (again, I know) how hard it is to swap over a diff centre from one VT to another, just for the fact that it's an LSD?

I know that older diffs like banjo's and other old diffs are fairly simple, take axels out and unlock diff centre form axel, but I wouldn't be surprised that it's a totally more complicated affair in the newer commodores.

If it turns out to be somewaht difficult, what would be the best/cheapest way to upgrade to an LSD (without selling the car and buying a different one :P).

Thanks!@#
