You mention possibly desiring a DC rear shaft but included no plans for a 3”+ lift.
Many members have been happy with he DC shaft built by Tatton.
If a standard, stock style driveline is what you actually need, the price beno quote earlier isn’t too bad for a driveline’s you will never need to replace. However, if you actually wheel your 80 and driveline damage is probable, seeking the least expensive, good quality solution would be prudent. By “good quality” I mean using toyota or Matsuba Ujoints only in the Toyota yokes. And if you went with a Tatton or locally built DC shaft use only Spicer joints in the DC head. I prefer the Spicer Life Series joint.
