Thanks!
My actual engine has 350 000 kilometers, this one only 250 000.
When I'll swap the cab, I'll put the "newer" engine and gearbox in it, just checking the clutch mechanism to be sure it is OK.
What nice is on this second truck is that it has everything still on it, and as some parts are really a PITA to find nowadays, I'll have enough parts for a long while...
