Yes, 35200 is the new part number, I didn't know they changed it. The tool slips into the groove in the handle in front of the clip, then you close the pliers and pull the clip out the back of the handle's groove. Thanks for the info on the clips being available from NAPA. I'm going past there today and I'll get some more. My buddy, who was a GM mechanic for years, calls them Jesus clips.....every time you drop one on the floor you say "Oh, Jesus!"
No one lives forever, the trick is creating something that will.
