Caliper Installation

I am in the process of converting the front of my 72 Duster to disk brakes. I purchased the kit from MP and followed the instuctions, However, the calipers mount on the front rather than the back side and now the brake hoses are too short.
What would you do? Dis-assemble and change the left and right spindles so they mount on the back or get new hoses? Does it make a huge difference as to the caliper mounting front or back or is it just a preference. While getting longer hoses may be easier - if you were doing it - what would you do...?
Am I over-looking something else?
Thanks,
