Help with chassis dirt dams for Ultima Outlaw

[sandkil]

I will try to fabricate new dirt dams and need help with dimensions and angles of the dirt dams for the Kyosho Outlaw Ultima (Utima ll chassis).
Measurements of the bottom part is easier as it sits on top of the chassis,
but I need the angle of which it flares upward (front, sides and aft) and the height of it.
Any help is appreciated.
