Auto parts manufacturer Arvin Sango says its plans to open a plant in Henderson are on hold for now. 

In February, the company announced plans for a Chester County facility that would create 40 new jobs. 

The Henderson facility was supposed to make parts for the new Toyota plant near Tupelo, Mississippi.  But Toyota has changed its plans for that plant.  Instead of making the Highlander SUV, it will now manufacture Prius Hybrids. 

That means parts makers like Arvin Sango must re-bid their contracts. 

Chester County leaders say they are unsure when or if plans for the plant will go forward.
