If your'e planning on making customs shells/housings for console, the new FrankenLaser is ideal for you.
It will not fit inside the normal regular shell, well at-least not without heavy modification.

It works and performs like a brand new 'stock' laser mechanism with great FMV playback

There is a small potentiometer on the laser and depending on your current setup, this may need tweaking a little bit to get full performance. This can be done with a small screwdriver giving it 1/8th of a turn in either direction until desired.
