4link can be done in the front, but it's no piece of cake due to the engine and stuff being in the front, less space. i'd like to think that radius arms and coils would be pretty easy to do with a straight axle though
if you want to do any flexing, that push pull junk has to go. just buy hysteer components, unless you have a buddy who's in a machine shop it's probably just cheaper to buy the arms, they're around $199 a set now. you can get the whole kit(minus the steering box) for $399 from
