As for the "old skool" front suspension, it might look easy but.....
1.) To get small tires to work, the steering blocks need to have .030 machined (dremeled) off of them.
2.) Setting castor is a little easier, just add shims under the front arms. Possibly use the old style castor shims from Associated, if you can find them.
3.) Same with setting camber, break out the shims.
Like with any front end it still requires workto get it just right. But it is a stout front suspension and will take alot of abuse while still remain usable.
One more thing, the molds used are very old, so check the arms over carefully to make sure that they are equal to each other and don't have any flaws.
