big let down car will not move now

Up date jacked up front of car, was able to rotate both front wheels freely, no problem there, jacked up rear of car put on jack stands, could not rotate either rear wheel, was sure the rear brake shoes where locked up took off both rear wheels was sure I would not be able to pull off the rear brake drums, but to my surprise both can off with out a problem brake lining was ok wheel cylinders where not stuck out, took notice that there where deep grind marks in the out side of both rear wheel cylinder they where fresh with metal fillings there , finally found out that as I was tighting the lug nuts acorn type on to the too long wheel studs that where not the press in type but the threaded type since they where to long as I tighted the lug nuts the studs would back out into the wheel cylinders on no both side and when I tried to move the car the the head of the stud would hit the wheel cylinders and caused the deep gourge to them and stop /block car from moving ! now I will need to replace both wheel cylinders and either see if I can install shorter wheel studs or use a cut off wheel and trim them down to the correct length !!! surprise surprise
