SIDE SLIDER LOCK MECHANISM

Are the Door lock mechanisms all different? I have an extra rear door lock but need a side slider lock. I have a 2005 3500 van.

There are four different part numbers for the front door actuator motors, (05133510AA to -12AA, plus 05133986AA)
((MB # A 001 800 35 75 , A 001 800 39 75 , A 001 800 38 75 , A 001 800 34 75 )

There is one number for the slider's actuator motor: 05103756AA (MB# A 001 800 25 75)

... and one different number for the rear door's: 05133998AA (MB # A 001 800 24 75)

added: a forum member has actuators available for sale: https://sprinter-source.com/forum/showthread.php?p=784555#post784555 and scroll up a bit.

The electric part works but the hook that keeps the door closed doesn't recycle to open on it's own. It needs to be pulled as you pull the door handle. Otherwise The hook just bangs on the lock and the door doesn't close
