Ok, so I've looked high and low and found nothing on the forums or net in general. Vehicle:1977 pb300 sportsman maxivan #3300 front axle My issue: Front Upper Control Arm Ball Joint failure means new front upper CA assy is needed. Conflict: I cant find 'vehicle specific' replacements but have found several for other model years. What I am needing to know is what year changed the control arm design in the B vans, what's gonna work? Thanks in advance!
