when I adjusted the wiper arm, the piece at the front of the arm cracked, probably from being brittle from the sun. is there a separate part number for this? (its about 4 inches long and clips in to the front part on top of the arm, i can get a pic if you'd like)
or do I need a whole new wiper arm?

Are the numbers on them not P/N's? Mine show DRV side-22122606LH Pass Side-22122607RH Hope this helps.

 

I tried them in gmpartsdirect.com, but no results. thanks anyway

 

The cap that goes over the mounting nut?

GM PART # 22122401 RH
GM PART # 22122402 LH

That's the only other part I see besides the arms:

GM PART # 22155458 LH
GM PART # 22155459 RH

 

Mine is a 93. I wonder why they have different P/N's?

 

Cast or embossed numbers on a part are not always indicative of the real part number. Plus numbers can change over the years, as well. The above numbers are listed for 93-97.

 

Gotcha Thnx

 

thanks
