Today we replaced calipers,pads,hoses and steel lines on my friends 1983 chevy k20 pickup.
So we started to bleed the brakes and the bleeders just unscrew out of the calipers.
How do you keep the bleeders from unscrewing?

You must unscrew the bleeders enough to allow fluid to escape. You do not unscrew them all the way. Have your friend pump the pedal until he feels resistance and hold it. Then you unscrew the bleeder, when the fluid quits coming out you screw it back in. Repeat this as many times per wheel as it takes to establish a firm pedal.

I am going to use a Motive pressure bleeder my problem is the whole bleeder assembly is unscrewing
out of the caliper.
Most of the stuff I work on the bleeders are so rusted in they break off before they unscrew out of the caliper.

The bleeder fitting is supposed to be just loosened- but it IS supposed to unscrew from the caliper, else no fluid could escape, savvy?

If you're saying the bleeder is loose as soon as you begin to unscrew it, remove the fitting and carefully wrap the threads w/teflon tape- being very careful there is no tape below the last four threads on the bleeder fitting. This will tighten and seal the bleeder fitting into the caliper port, so it will not draw air past the threads.
