That is a common issue and typically covered on B/E body sites, and has been covered by Mopar Action and in Adkins
performance book.
Typically you have to swap the spindles side to side so a stock hose will fit...
The issue with the caliper location and the sway bar stems partially from the fact that with the change of the structure of the K-member
the 67-72 A-body (and I hear on the 66-69 B-body) is the sway bar was externally mounted to the bottom front of the K-member and used
a shorter link and bushings... The 1973+ units had the bushings mounted in the 'web' between the body mounting bolts, and the sway bar fit though
the hollow void in the spool mount K-member and used longer links and bushings... so when mounting the later suspension to the earlier version of mounting
some conflict occurs and either some grinding to swapping spindles and mounting the caliper opposite of their design is in order...
Oddly what adds insult to injury is that mopar would recycle their FSM illustrations year to year and using the front suspension and disc brake illustration from 1974
and labelling it F/M body in 1978 isn't accurate when trying to reassemble your Aspen...
I would mock one side up and see if the hoses will work... and if not, remove and swap the other assembly on and then see if the hose works better...
