Upper control arm

[87bucketgta]

Hey guys I hope I dont have to stupid of a question, I have an 83 ho, redoing all the bushing and balljoints and soforth. My first question is does anyone know what size drill bit to drill the rivits out with I dont have a air hammer to get them out with, my second question is when I took off the control arm the actually shaft looks bowed or bent alittle in the center, is this normal or is it supposed to be straight. Thanks in advance

The shaft should be straight. They are easily obtainable.
As far as the rivets, grind the head down and punch 'em out. The new nut and bolt should go right in.
