Guys thanks for all the input. talked to fran. it's a GM ball joint out of a 1990's model pickup. so it shoudl handle the light load of an SLC. That hole is pre-drilled by GM/TRW.
It being heavy duty, i think drilling it in place is an Uber bad idea. I'll just put a jack under the ball joint with the car jacked and use the shock to push down the ball joint. Then i can get grade 8 stuff stacked to make the castle nut meet the pin. Looks like one 1/2"-20 and 1 washer will do the trick
I shoulda done this before driving and putting a load on the balljoint but i was a little anxious to drive. I just hope the tapered stud hasn't become force fit. I'll let you know how it goes.
