Practily every older Venture I see has rust in front of the rear wheels at the rocker panel. Mine was S.I. rejected for same. I repaired it,very unproffessionally to pass S.I. and it passed. I looked to JCWhitney for pieces to do the job better and they don't carry this part. This is such a common problem,somebody must have an after market part for this, be it metal or fiberglass. This is a 2003 LS w/ 57,000 plus m.i.
