brake line question

[ride300exrider]

i have a 300ex with 400ex arms so when i buy brake lines like braded ones should a buy 300ex stock lenths 2, or do i buy 400ex stock lenth? im lost on what to buy but i think its 300ex stock lenth.

Either one would work. But if you have a choice i would get +2 for the 300ex.
