I believe they will not work...got an email from thunderbike...
Hi Bob,
I'm afraid the riser centres are wider on the Touring so our TBars aren't suitable.

Kevin(from Thunderbike) Now their T-Bars will fit all years of the Rocket Classics..just not the R3T..AND the Thunderbird Bars will fit our R3T..therefore I believe the Thunderbird and the R3T share the same center spacing..therefore they may not fit the America/speedmaster...But as Friar suggests there are several aftermarket resources available..just my 2 cents worth!
