67 Dart Disc Conversion brake hose too short

I was under the impression that it was a bad idea to move the caliper to the back. The reasoning I have always heard was that it was designed to be towards the front for a reason. I only ask because I am getting ready to start this swap onto my '65 Barracuda along with adding a front sway bar. Everything was ordered from PST. It will help to know ahead of time before I but the brake hoses.
I am starting to buy a few things each week until I have all the parts ready. When I bought the disc brake caliper hardware kit, the "metal plates" are a touch wider than the originals that were rusted to the calipers, is that just an aftermarket difference? Has anyone else noticed it? Thanks for any info.

I was just thinking about this the other day...
Theoretically the rotation of the wheels and the resulting forces when trying to stop COULD cause an upwards motion and unload the wheels and therefore lessen available traction with the calipers mounted towards the rear. And the reverse for the front. But According to the calculations I was doing in my head While I was thinking about this, the differences in tire loading would be so negligible that it wouldn't be noticeable even on a Formula-1 car.

For the most part the only reason car manufacturers place them where they do is packaging.

Hope this helps!
