So when ordering a front 1350 DS with a D30 front , im sure it's not just plug and play. What is it that I need to make sure it has? So it will fit. Bigger yokes... Please excuse my lack of knowledge.
Would the rear be the same?
Yes, both yokes need to be changed with a standard swap/upgrade. I know Adams has a unit that uses the existing front flange with an adapter and you just have to swap the T-Case side, but it pushes the front U-joint back a bit.
Call the manufacturer you choose to go with and talk to them about measurements before you proceed. While a driveshaft swap may seem easy to some, it isn't to others. If it is your daily driver, I would take it to a reputable shop and have it done or have an experienced buddy help you out.
