anyone know how high and wide the opening is of the hole in the middle of the 89'+ bumpers are?

trying to work out some last minute IC's configs.

 

ill just go measure.. its night time.. hot.. and cloudy.. no light.. so u better appreciate this!

[10 mins later]

15cm by (3 x 15cm + 13cm)
=
15 x 58 cm
(thats going along the angle of the hole, not vertically)
