Although this vehicle was manufactured in Mexico, it was purchased and driven in the Great White North Eh. Canada
I have already purchased left and right lower control arms complete with new Ball Joints and they are staged for installation.
My problem is going to be rust, I have watched all the YouTube videos and having worked on rusty vehicles for over 60 years, I am no stranger to removing these types of parts.
Would you have the size and dimensions of the hardware nuts and bolts and where they can be purchased? The ball joints came with new pinch bolts and nuts.
I am thinking on the driver's side I will have to drill a hole in the inner wheel well and give the mounting nut on the vertical mounting bolt a Muriatic Acid bath.
I have used this chemical before, and I am aware of the precautions and PPE required to work with it.
Any suggestions would be helpful.

They really don't give us the nut and bolt sizes but, in the instructions, to replace the lower control arm below they do show how the job is done and the torque specs. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.
