Definitely not your everyday beam front spindle. They look like they possibly started life as VW Thing balljoint spindles that someone has cut, ground, reinforced, and converted to uniballs. Finding replacement spindles (and arms) could be challenging as they're probably a one-off creation. Hope this helps, Good Luck!
ok I almost bought some thing spindles but then realized that my spindles have four mounting holes for 2 wheel cylinders. So here are some more pics of the spindles. anyone have any more guesses. thanks!
they are bus ,cheap way to build big arms and spindles,old school but works,ive known acouple of people that have had this set up on baja bugs and one thing,a guy in san marcos used to have a shop that used to build them.some ive seen use they stock ball joints at the end of the arm.
