PS2 Disc Drive Removal Help

[superhuman]

Hi,

Dunno if this is in the right place but could see anywhere else where it might go.

I'm trying to remove the disk drive from a ps2 i have but i can't see how it is attached from the inside and how to release it, because it is jammed and i either need to replace it or try and fix it somehow. Also if i do need to replace it, does anyone know of anywhere that sells replacement drives for the ps2?

Cheers
