From R&D Unique, a cast metal timing chain cover with an electric water pump.
Two separate pieces.
The timing cover has an included 2-groove crank pulley.
The electric water pump includes a 2-groove pulley and a radiator hose outlet.
For the hose, use this 2" diameter soft line. It's hollow end fits right over the hose outlet.
Both items have excellent detail.
