My c20 suburbans rear upper shock on the drivers side bolts into a bracket on top of the frame.On the passenger side it bolts directly to the frame.Would there be any issues if I drilled a hole in the frame on the drivers side to mount the shock,due to the mounting hole in the bracket starting to rust out and causin the shock to wobble around.I have a regular leaf spring set up and load helper air bags if that matters.
