Maybe some has already worked this out but HD list a whole bunch of service sheets on the web example:

LIFT ADAPTER KIT FOR DYNA TC88 MODELS  J0151 is below link 

http://www.harley-davidson.com/en_US/Media/downloads/Service/isheets/-j01521.pdf

If you change the last few  "J01521" characters on your browser you can bring up other sheets which is really handy when your lookin for part numbers.

example 

FXD (Dyna Super Glide) TACHOMETER KIT J01522

is
