Help I'm stuck... literally

[Spalma916]

Hey guys you've helped me out a lot in the past and I'm hoping you can help me out again.
I have a 69 c-10 longed 296 with Muncie 4 speed. I've been slowly restoring it on the side of my house and starting it up every weekend. I just loaded it up for the first time to move (got a new house) started right up like a champ but when I put it in first and tried to go it felt like,my tires were glued to the ground, it kinda pulled forward like it wanted to go but won't, also tried in reverse and the same thing. I'm parked on dirt and trying to push it in neutral doesnt work either. Only thing I can think of is the brakes siezed....... idk, but if anyone can give me some tips that'd be great, I can't leave my girl to long alone.......
