Whats needed to give my base model 4 lug an lsd and 5 lug
 

I have an 88 base model se, was wondering what i need to have an lsd on it (miata torsen lsd , turbo II lsd, gxl lsd etc )

i want to get the 5 lug conversion and an lsd, but was wondering what else i needed, if anything ( halfshafts, axles etc)
