"The assembly line the unit was built on can also be represented by a letter.
Most units built at Arrowood Plant use a letter in this position."

An example is my '82 Super XL-925 ... UT:10415C .. SN: HD2220299

CORRECTION to the example above, it should read:

My '93 Super XL-925 ... UT:10415-C .. SN: HO2220299

Correct. The “C” suffix in the UT didn’t start till 1989, so it couldn’t be a “D”
