Called Carlos at TPUSA in CA this morning and he said he would check into it but first said they have put the manifolds on hundreds of bikes but he wasn't sure about the 05 Speedmaster. He called me back an hour later and said that sure enough the 05 speedmaster has a different air box and they would not fit my bike.
I guess they will have to change their web site info to say they do not fit at least 05 speedmasters.
Maybe some one out there knows the details on which bikes have different air boxes between years and type Bonnevilles.
I came very close to taking them from the shipping box to my buffing wheel for polishing. I ordered them unfinished so I could. At the last minute I held them up to see how they would fit and the rest is in the forum thread.
This shows that it is a good idea to take your time and look at thing like this closely before going through the work necessary to install pieces and parts we get for our bikes. This would have been quite a few hours of missed riding time.

I was looking forward to that advertised improvement.
Carlos did say that if I wanted to use their air box removal kit that they would work but that is not what the website says.
I would like to hear from anyone who has put them on a 865 engine with stock carbs to say how they improved performance.
roundy77 asked about pictures of the manifolds - you can see them on Brents NewBonniville.com site.
