G'Day Guys

Been a reader for quite a while, finally decided to get involved. Have a few questions for the brains trust, but if you guys could just link me with the threads i need that would be greatly appreciated.

Currently rocking a 1999 RD28T, incredibly well looked after, single owner little unit. I am doing the barra swap and cant seem to find clear info on what i need to do/buy to make this happen.
I originlly had a '01 ZD30 and started prep with that being the basis. NOW, the waters seem to get muddy when it comes to the RD28.

So if i could grab some guidence that would be amazing!
