4-Link, Rear End Question:

Im in the process of putting my car back together. It's just had a body off full-wrap; all of the critical suspension parts have been reinforced also. My question is with regards to an appropriate rear-end linkage set up. As of now, everything is stock. Will I need to link the rear-end? Should I expect axle slippage? I'm running a mild 2 pump six battery set-up on a '66 rag. As Im reassembling the car, Im trying to account for any minor detail that could potentially be overlooked. Basically, I want to do the car the right way. Post pics or feedback. Good lookin out
