1997 Ganant service manual

Hi everyone...It's been a long time since I've been on this forum and its good to be back.My question is does anyone know where i can get a service manual for my car(preferably free) because I'm trying to remove my headlight assemblies to try and clear up the inside of the glass but i can figure out how they come out.I did remove the screws that hold them in but something is still holding them in and i can't figure out what.Thanks in advance for any info guys.
