upper control arm

I already made the swap
sbp to bbp with disc brake and all it takes

but in there explanation they are telling
it aint suppose to fit with disc brake

so Im confuse

and why mI surching for control arm?
the previous owner weld the ball joint to the control
arm for a quick fix the ball joint pop out,the treads were
strip or something like that

so I found those and they seem to be ok
not as good as to OE were but...
and alote cheaper tubular ones
