Brake line routing: old vs new

[Canada20]

Hey all. I swapped in the front crossmember of a '72 C30 to do the disk brake conversion and I'll be using the MC/booster assembly from the same (unless I find a newer one to fit, of course). It looks to me like GM changed the routing of the brake lines and location of the distribution block somewhere between '69 (the year of my C20) and '72.

Are there any good sources for the differences between these? I think I'm going to try and replace all the lines on the truck as the old ones are...well....old and the system has been open to the elements for some time now.

Many thanks,

Greg

just did my own disc swap. from my experience i would say just buy new lines at auto zone. i reused the front lines but replaced everything from the master back with new lines from Autozone. about 12 feet of steel line in 2 peices was $10. comes flanged and with fittings on it. they have several different lebgths. be careful bending it. if you bend it by hand do it slowly or you will kink or break the line. good luck. im lovin my disc brakes!
