I have found a very good replacement part for the Upper A Arm Bumpers. The top part is identical to the originals the bottom can be used as is or after a few minutes with a belt sander can be ground to the V shape as the originals were. The replacement bumpers are for a 2001 to 2005 S10 Sanoma or Blazer. Part number is on the box in the photos. First photo is the box next to the box is the S10 part and an original. Next photo shows my sanded down part next to an original.
