cutting down radius arms. How far is too far??

I'm in the process of mocking up the front end on my 35 pickup, and I need more clearance.... If my radius arms are 34" from axle pin to heim bolt am I gonna be ok????

 

bttt i would like to know too

 

can anyone answer this

 

Length is not so much the issue. You want the rear mount of the radius arm as close to the steering arm (with steering centered) as possible so that the steering link and radius arms travel in the same arc. The more differance, the more bump steer. You also want them as close to parallel as posible.
