Looking at the front docking hardware and I am puzzled.

2 pics below for example. There seems to be 2 different kits. What's the deal and what is with the extra thin black piece in the second pic?

 

If you want a solo detachable hardware kit,you need 58303-06. If you want the two-up detachable kit,you need 58304-06

 

58304-06 shows as the rear set that is used for the tourpak. I want to be able to quick detach a passenger backrest only and that part appeared to be 58303-06 but I am finding two variations.

 

Where are you finding these two versions? Agreed they look different, which leaves me suspicious that one is true and the other is possibly the wrong kit.

 

i have seen in various online sources. THe HD (dealer site) kit does not have the extra piece. I am wondering what that is for

 

Assuming you are putting this on your 08 ultra, I would use the 58304-06, yes it allows a tour pak, but it can be used for a passenger backrest as well. It includes all the necessary hardware. Tis better to have and not need than need and not have.

 

I actually have the 58304-06 parts already. I was noticing that there is another set of hardware and wasn't sure if I needed both for the occasional passenger backrest. Then noticed two different versions of the front hardware.
