MPC60 Mk1 replacement backlight size?

does someone know the size of the MPC60 Mk1 replacement backlight?
i want to cut my backlight myself but don´t want to open up the display,
unsolder the backlight, solder it back in and order some backlight foil..
if possible the outter size and the inner (just the illuminant stuff).
that would help me alot!

can anybody help me? thanx!!

after lamination .. mine measures 5 1/8 x 1 /18 inches .. so subtract a few mm for the laminate to work

thanks for the info!!
but i figured out that 1 /18 inches must be way too narrow, i think..

i think he meant 1 1/8

yep i think so, too but 1 1/8 inches is still too narrow.
the part of the backlight that you can see from the outside of the display is
even bigger.. the length of 5 1/8 inches seem to be the right size.
