My PLX was a near perfect fit, snug side to side, just needed to pry the louvers out and install it in their place. I left the top two as you can see for space fillers, i broke them all out and glued those back together, d'oh.

Wires were within reach to the CD Player wires, so i just wired it in with that, used some moulding tape from a hardware store to secure it.
