'70s Murray Wildcat bike project?

anyone know anything about these bikes or have experience fiddling with em?

my friend just gave me one for free. the pedal assembly is locked up and it needs two new wheels. I have always wanted a muscle bike and my friends mom restores shwinn stingrays but she refuses to help on this bike as its a Murray. I plan on making it a rat rod kinda. the fenders are rusty but still have chrome on them.I think it has the potential to be way cool. Ill get some pics up when I get it home here in a bit
