Rear axle brake lines
the 8 3/4 will be the same. i got a set from from finelines. tell them you are going with rear-disk and they'll put the correct ends on. and you can get them in stainless. just check out the location of the ventplug/brake line block they change in 1970 and place them on the axle tube and 69 and early on the top of the housing.
