dimensions of LE landing light

The used kit I just bought already has leading edge cutouts for landing lights, but they are a nonstandard size and shape. can somebody tell me the approximate dimensions of the lens cutout on the ductworks kit?


Also, for a wiring solution, is it advantageous to buy the vans wire loom or just roll your own? Here's what I'll likely end up with

LED Leading edge landing lights
LED nav/strobes
heated pitot
Aileron servo
Magnetometer
Archer nav antenna

Shoot me an email and I'll send a pdf of instructions/templates. They are old and you will need to judge if they are what you need.
