different brake lines with drop spindles?

[no_rice]

so, i just ordered the cpp modular drop spindles and brackets for my 70 gmc. it already has shorter coils on the front, and has been swapped over to 73-87 a-arms and disc parts.

im not sure my brake lines will be long enough to reach once it comes down 2" more(could have used 3" but needed the narrowed track more then the extra inch...)

i thought i read somewhere about maybe the 3/4 tons having a longer brake line, or maybe it was the 4x4's?

guess im trying to get ahead of the game and have my plan in place if i decide they wont reach since im wanting it together for a trip in a couple weeks...
