Fully rebuilt DS21 motor with new pistons and liners.
I was going to restore another D but I am not going to get to it. I rebuilt this motor to go in that car. 
The motor is located in my shop in Downers Grove, Illinois. If someone is interested I can pull it out and get better pictures.
I also have many other Citroen parts for sale including (but not limited to) two pairs of fenders with European headlights and a rebuilt Weber carburetor, not to mention the car that I was going to restore.
It’s best to call:
