Help with Lower Control Arm Mounting Holes

[Got9lbs]

I have a 1991 notchback that I'm installing a MM extreme duty adj lower control arms, tq arm and panhard bar setup. I started to install the lower control arms and noticed that the bolt holes are oblong, there seems to be about a 1/16" to 1/8" too big. I have the correct bolts they are the 12mm ones. I took off some south side lower control arms which came on the car and I'm not sure if they caused this to happen or what. I need to know if this is suppose to be this loose or is this something that needs to be repaired? This is my daily driver in the summertime, has a single turbo shooting for 550-600 at the tires. If I'm supposed to fix this how would you go about doing that? Thanks, Karl

You could just leave it, it won't move unless it's loose. If you wanna fix it, put the bolts in tight with a washer, then weld the washer to the frame.

i did that, then welded the torque boxes and put the battle boxes on it also. i also steped up to 1/2" bolts for the contrle arms...
