74 power steering
So it looks like I have 2 leaks. PO told me it leaked but I topped it off and made it 1500miles home and 2months before I heard some squealing. I believe this crappy homemade seal might be one of the culprits and the other leaking is along the front bar probably an o-ring. Didn't know if there were any known issues I should address or if there are notorious leaking spots. Anyway I here are the pics of the box. I can get more if it'll help. I appreciate any help!

Never mind, I see it better now.

Hopefully someone with some experience with one of those steering boxes will chime in for you.

The steering gear box used with 1973/75 F100 4WD & 1975 F150 4WD is the manual type, because it has nothing to do with Power Assist.

Pardon my ignorance on this, but I can't for the life of me get this power assist pump off. I disconnected the 4lines coming in and let the PS fluid drain. Then do I just unbolt the 4 screws on the side closest to the brake drums? Because I can't get them to budge nor can I get a grip on them. Anyone have any videos or how-to's for removing it?

Do you have any tips to get it off?
