Hi Danuel

What happend to your van ? Seems like it won't move yet

I will have a look to tell you more about this engine. You will find the exact number on a tiny plate witch is located on the left side of the cylinder head, just behind the oil filter. number 616.xxx
Are you looking for another gear box for your van ? I know a 4 speed one for sale if you want. But becarfull : there is two different types, the hight speed one and the low speed or hight torque one. Don't do a mistake or it won't be funny.
The gear box that i know is the higth speed one. To check what kind of gear box you allready have on your truck you have to get the numbers on a plate on the box.
Good luck my friend

We keep in touch.
