I have no clue what this part is called so I'll do my best in explaining it
my 1979 (basically) cdeluxe 4x4 k10 driver side "spindle" I believe it's called is cracked/bent. (the piece where the upper and lower ball joints sit in). It's not the axle housing itself. I plan on pulling the spindle piece off including the steering arm etc. I have a 86 k10 silverado parts truck that has this on but i'm unsure if it'll work. For some reason my dad is hellbent on anyparts after 80 working on my truck but I haven't the slightest clue so if anyone could help I would appreciate it.
