I put the Road King Tallboy bars 55954-00 on my road king sidecar rig last year after some forum searching and they fit without any cable or line changes.
When they arrived and I installed them, I thought I was going to hate them and wondered why anyone on the forum would possibly recommend them and why I didn't just buy some cheap 10" mini apes from any of the retail outlets.
A couple of long rides and some minor adjusting of the angle on the bars and controls and I can say that the forum was correct as usual. These are great bars for a road king as long as you don't care about looking cool which I don't have to worry about on a purple bike.
For reference I'm 5'10" and built like an orangutan with long arms and short legs.

 

Outsanding info! Thank you, these bars were pretty high on my list.

 

I think they fit rather well... Nice job..
