get a dip stick that matches the oil pan?
Changing oil pans from front sump to rear sump is common with the 3.4 swaps. Once you track down the part numbers, it's super simple to swap it over. I'm not sure if more or less is involved with a 22r motor. On the 5vz, you swap oil pickup tube, oil pan and dip stick, and on certain motors, you have to redrill the dip stick hole.
