:ö:
here is a drawing i made on MS Paint (sorry i don't have an AUTO CAD program

) on how i made my universals for my front tires to be able to drive and steer as well ...
this will be an easy task if you make it on an allum tube, you don't need make part no.3 you can solder the connecting rod in the middle which will act as your cross joint(?)..
if you got any question, i'll be glad to answer it!.
