OK.... I just swapped in a full width chevy dana 44 under a scout. The stock front axles had drum brakes, and the chevy axle has disc brakes of course. Well the problem I am having is that after bleeding the brakes they won't back off. As soon as you hit the brakes they just stay tight, and won't let go when you let off. Anyone have any experience with this or know what I might do to fix it?

Drum brakes masters have a check valve that holds 2x the back pressure of disc masters.
You can:
swap for a disc master
remove the check drum valve and install a inline disk check valve.

Can I find one of the inline check valves for disc brakes at pretty much any auto parts store? Is there a certain one you recommend?

I use this one:

Buy a new master cylinder for a 74'-80' Scout II. It will bolt directly onto your existing brake booster. Should fix your problem.

Remans are ~$20..

Might have to change the fittings on your brake lines from the prop valve to the master (though you should consider going to a disc/drum prop valve, too) - I can't remember.

When I did mine I swapped to the SII disc/drum master AND SII disc/drum prop valve, which did require changing the rear brake hardline fitting that goes into the prop valve
