brake line length

[exdrocca]

Hey guys, I would like to know if the length of FRONT to REAR brake line between a '69 c10 2wd longbed, with drum/drum setup, and a 71-72 c10 2wd longbed with power disc/drum would be a different length? I should add this is a 2 piece brake line. Brake line is starting at dist. block/prop valve and stops at the brake hose at the rear end.

I did a search and found a thread with diagram of all the brake lines and measurements for a 71-72. Looks like the same set up for my '69.

What I'm getting at is that I ordered a pre-bent brake line front to rear for a 71-72 (would be installed on a 69), and with the 2 pieces I only get to the under the oil pan. I'm about 20" short, if not more. Not sure if they sent the wrong lines or it's just a different length for my year and I made the mistake.
