Greetings,

Most of the "specs" I've seen simply give the M400's Length, Width, 
Height, and Weight.

So unless your tron has gained a few pounds or inches around the 
middle (like most of us) it should still be within "factory specs".

However, I do have schematics, if you need them please email me and 
send a picture of the circuit board.

Regards,
Jim
