Do you have pics of your brake lines for the Dana 25? I did the swap on my Dana 27. All i did was bolt the calipers on and run the proper rubber line from the caliper up to the frame, where i connected it to the existing hardlines. Wasnt hard at all, and worekd out great. Only issues is you might not get enoguh push from your master cylinder, unless you swappped it out already. Some people seem to be fine and others don't. I wasnt good so i went with a hanging pedal setup and a later disc brake MC. Defiantely 1000%% over the 9 inch drums.
