I currently have a 2.77 9bolt with PBR calipers. I'm swapping in 3.27 9bolt with the old style steel calipers but I'm gonna swap over the PBR pieces. Can I use the "old style" brake lines?

I don't see why not, and it would make like a lot easier.

Use them, nothing specific about PBR brake lines.

Forget the below. I finally understand--hey, it's early! PBR to PBR should be no problem.

I may be way off base here, so take what I say with a grain of salt. On my ten-bolt, the iron caliper on the driver's side required that the hard line go to the front of the axel, and if I remember correctly, the hard line went directly to the caliper. When I swapped to PBR's, the hard line on the driver's side went to the rear of the axel and required a hose. The following thread will show what I mean about the PBR lines:

you could always get new lines

same here on my 88' 9-bolt. the drivers side line was a hard line all the way to the caliper. the pbr used a flex line. i replaced the hardline with one from a pbr equipped car.
