I had to modify the pump/filter mount due to my camper mounts but its tucked up nice and high.
The mounts they supply are horrible. I never use them.
I just installed all this stuff on a 3rd gen yesterday... that delco box is a beast.. I think it takes after what they are putting on the 4th gen trucks now. The pitman arm shaft is huge, I think I needed a 1-13/16" socket for the nut. beef!
I have heard a reference to a 3rd gen box upgrade on the second gen trucks but I have not researched it yet.
