Ran a search on Cip1... here is the part number of the missing parts... just the arm and blades... may help when you call around.

also near Greg you have SoCal imports... who sold many parts to Kirk for his cars... and I’m assuming he may work with Greg. Their parts are typically Chinese made... but for the price you can grab the pieces you need and keep the rest for a rainy day. Call them, they also have a great help desk and they know our cars,
