Re: 71 72 brake lines

I don't believe there is a difference.

That's what I thought but if you go in the lmc catalog and look at the brake lines the back three lines have different part numbers from 71 to 72 and I cant figure out the difference in them

Re: 71 72 brake lines

from what I know it's where the "t" is mounted on the axle.....On the Dif or on the Axle tube

I thought the same, but I thought the hardline connected to the flex line at the same hole in the frame, regardless if it's a 71 or 72.

Re: 71 72 brake lines

In 72 the hardline came across onto the cross member behind the axle about center like pictured in post 7 of the linked thread. The hose drops from a tab formed in the center of the crossmember. The bracket for the other end of the hose was mounted on the differential. 1967-71 had the hardline end right where the crossmember meets the passenger side frame rail and the hose bracket was welded to the axle tube between the diff and pass brake drum.
