8-3/4 Rear brake drop hose to short

I would assume that with shocks removed and suspension hanging at full droop the hose would still have slack. As I understand it the earlier 69ish and older with the breather on the hump had a longer hose and the later year had a shorter hose.

How about a photo of the bracket in place

according to Rock auto:

67 rear hose is 14.6" long
71 rear hose is 13.7" long ( looks to be same fittings as 67)
74 rear hose is 14.5" long but has an integral distribution block attached

can you supply a photo of the mounting bracket on the body, perhaps you have it installed upside down or the like?


found this 70-71 parts book
is this your routing? If your "T" was facing to the drivers side, might be an issue.

Also are you using stock springs and shackles?
any chance the bracket you are using is not the correct one?
