Was it plug and play? Or did you have to make modifications?

I'm planning a big project to do the head gasket and timing chain. While I'm in there:

Rebuild steering pump
Alternator
Belt tensioner and shock
Pulley plate (?) Right below the distributor. Mine is obviously shot.
Rebuild the head

Looks like the next repair has to be the tranny though.

Can't wait to get the mechanical stuff out of the way. She's going to be a all black benz with euro headlights.
