Need Jammin, Mugen, Losi, etc truggy arm dimensions, please help!

Awesome work so far guys! The mugen arm is actually offering some interesting possibilities due to the pillow ball design.

I want to keep my 4WS I have, but most knuckle/chub designs build in a lot of caster. fine for the front, but I was trying to figure out how to deal w/ the rear (where knuckles would also have to be turned around..)

Do you happen to know the "B" length of the upper F arm Nard? If you happen to know the pillow ball center to center, that would be awesome too. Its a pain not being able to see these parts in person!

Thanks again.
