Axle Hard Lines?

Im putting in a 9bolt disc brake rear with the 11.65" rotors . I dont have the axle hard lines. Just wondering if anyone knows the correct lengths/fitting/flare for the the right and left side. Thanks

Sorry, I don't know the particulars. IIRC, I purchased new from http://www.finelinesinc.com/

Re: Axle Hard Lines?

They are bubble flair ended lines. The tool to do the flairs is espensive (around 70 i heard) so instead i bought some straight lines around the same lenth that i would need from napa with the flairs and fittings already on em for a few bucks and bent them to the shape i needed. As far as what the actual fitting is i cant remember. I believe its metric though.

Re: Axle Hard Lines?

Anyone know which ones you would need? I dont know what year the rear came out of, but its a 9 bolt rear with PBR calipers. I want to put it all together, but am missing some brake lines like the OP. Anyone have any ideas?

There's no difference between 9- and 10-bolt lines. Check post #3 of the following link for a part #:

The axle hard lines are 3/16" and the tube nuts are M10 x 1.0 Bubble flare
