Exchange engines

These engines are normally marked with a VW recycle symbol and an X at the end.

Information from a 5/73 USA service bulletin issued 5/73:
Engines with the re-manufactured symbol, a letter, a number and ending with X, indicates a VW Exchange engine. Before Oct., 1968 the X was not stamped onto the block.

From April of 1972 Shortblocks were sold with the VW remanufacture symbol followed by a letter. No numbers were used, you were to stamp in the old engine number.
