I thought I posted already on this yesterday, but it appears I must have hit the wrong button since I don't see the post here.
That part number is the one cast into the backing plate, correct? It's just the part number for that plate, not the entire kit, and it is obsolete. Based on the part number suffix, I would guesstimate it is the plate designed to fit the 46mm throttle body used on the 2006 - 2007 Touring models as well as later Dyna's and Softails. I would also guesstimate it would work on the 2002 - 2005 Delphi throttle bodies which were 42mm if memory serves. What it definitely won't work on is anything with the current 50mm electronic throttle control throttle bodies, which were introduced in 2008 on Touring models and around 2011 on certain Softail CVO's.
Check the bolt pattern on the plate for the TB. The 50mm plate has a hole pattern with holes at 10,2, and 6 o'clock. The older TB's used a distinctly different pattern.
