This is for the archives so if anyone else months to years from now wants to do it because blacklines aren't as popular.

I installed a set of softail slim floor boards on my blackline. Scored a set with brackets off good ol ebay. All that's needed is the boards, brackets, shifter arm and brake arm. The stock rear brake reservoir works with the whole set up. Was a pretty simple swap and straight forward. I guess all new softail floor boards will fit any other softails. And vise versa.
So if anyone wants to do it, here's a lil info. Hope it kinda helps.

 

Thanks for the info. I've been thinking about this since last summer for my '12 Blackie.

 

heres a place to ask questions and post things since blacklines aren't the normal bike
