When I swapped my 1st gen open rear axle for the 2nd gen lsd rear axle, swapping the parking brakes was required, since the beds were different lengths.
After removing, and swapping them out, the brake shoes must have made a difference, as I couldnt adjust the parking brakes back to where they were originally set.

I just adjusted them by hand, and have about 14 clicks until full engagement.
I had read something like 16 clicks is what you want, but I was sort of limited, by being near the beginning of the adjusters. Didnt even know they made that fancy tool Josh
