hi everyone, i just finished upgrading my front with daizen bushings, replace lower ball joints and tie rod ends when i had an idea. maybe it is possible to cut grind and modify the old lower ball joint into a rca set. it might take some work. but it is an idea. unfortunately i threw away my old ball joints already. so i cant really do much now.
hopes this spark someone imagination.

 

not a bad idea but you would have to press the old ball joint out.
