Hi cruz-
Ive just done my cab doors (new cylinders) and tailgate (same cylinder, i just cleaned it up) and re-keyed everything to the same key. However, on mine at least, the tailgate lock cylinder is certainly different to the cab door cylinders.
The square peg on the end of the tail gate cylinder is a larger diameter, has a chamfered corner (so only one way to assemble), and the cotter/punch pin to hold the lock lever on is thicker and longer. i took a load of pictures of the dismantling, and thought id write it up on here for anyone whos interested.

Tailgate lock on left, cab door on right. Not a brilliant pic, but see the cotter pin hole and square section.
I dont
think i have a late rear lock, but other than my van being an odd one, this locks different alright..
