9 bolt and 10 bolt axle hard lines the same?

Does anybody know if the hard lines on the 9 bolt are the same as the hard lines on the 10 bolt? This is for 4 wheel disc.

Thanks.

Depends on the year. If they had the same brakes, ie PBR calipers, most likely the hardlines will match up. But if one had delco brakes and the other did not, then you'll run into different hard lines

Yeah I bought the 9bolt lines from Classic Industries for my 9 bolt and they don't fit, not even close. I'm wondering if I should try out the 10 bolt lines. Calipers are not changing.

Though the hard lines were for PBR's on a 10-bolt, the lines I purchased from http://www.finelinesinc.com/ were a perfect fit. More choices:

James I checked Finelines they have the same part number as Classic. FRA8601S. It doesn't look good. Wait a second, Finelines lists 8601 as Borg Warner with rear drum. Classic shows it as 4 wheel disc. Finelines shows 8602 as generic 4 wheels disc.

Ok I found a picture of FRA8602S and it looks just like what I took of the axle. I'll get the 8602.
