I recently put disc brakes all the way around my chevelle. I order the wilwood kit for both. I also ordered the master cylinder and booster and proportioning valve for disc/disc brakes from mp brakes. Now for my question. I was thinking of ordering a prebent line kit from whomever but could I use a kit from a 1967 with power disc brakes for the front? Would it work on my 66? Is there any frame differences that changed? Also should I get the front to rear line for a 66 or 67 to match the front. The back I will have to do by hand which is not a problem but I figured if I could use the prebent one for the front it would save me time. Thanks for the help.

no, because the 67 set up used a separate proportioning valve and I bet your kit has the combination valve.
