for the conversion you'll need:
t-case (both are strong, there are some quick sy's running stock t-cases)
output yoke that matches.
t-case adapter
t-case brace
transmission crossmember, some say that they are the same but i've seen both side by side and they are different.
propshaft
front differential OR the driverside axle, driverside axle tube and pinion flange to convert your front diff.
