Hey guys I know this subject is a common one.
yet I can't find a specific answer .
got an 07 fxstc with what I believe to be factory 12" apes...
my front brake line is metal from reservoir to bottom tree, then transition to soft line to caliper.

I'm swapping to a different style 12" ape(metal parts will not look right with these bars), and need a 1 piece brake line for this.
I'm not able to measure my bike, due to working out of town.
really want to get parts ordered so when I'm back in town I can install everything

can anyone help me.
I'm getting mixed info from different companies .
some say 47.5", others say 50"
and I also have -2" tubes installed

 

There is only one way to safely and confidently buy the correct length, which is to measure YOUR bike when you can do so. There is one lesson I've learned, courtesy of the well-meaning members of HDF, that mods of this sort don't have a single solution! You have too many uncertainties and unknowns for anyone to give you good info. Wait until you get home! Spend once, spent right.
