I have a 1968 Mustang Fastback that had been sitting for 12-13 years.
All the brakes are "Locked" or "Frozen" Is there a easy way to unstick
the hubs for inspection for probably replacement of original drum brakes?
Thanks

By frozen, I am assuming that the car is off the ground (jackstands) and no wheel (front especially) will rotate?

I would start by opening the wheel cylinder bleed screws to relieve any possible hydraulic pressure (frozen MC). At the front, take a large pry bar and insert between the lugs and see if you can free those. The rear may have frozen brake cables and require a different procedure.

If still locked, you will have no choice but to remove the bearings and pull the hub off with a puller. Try to back off the star adjuster before this. If the adjuster is frozen, you may have to take a hammer and chisel and knock the adjuster from between the shoes.

Actually, it is going to be about the same procedure for the rear. The only other factor is the possibility of the cables having frozen. Again, knock the star adjusters out to try and relieve shoe pressure.

A lot is going to be damaged, but there is no other way.

Remove wheel... On a 45 degree angle to and on the edge of the drum hit it with a 3-4lb shop hammer several times all the way around... Rust and dust will fall but your hub will turn...
