Need part # confirmation for brake shoes and wheel cylinders
 

Found the parts I need at gmpartsdirect.com to replace my rear wheel cylinders and brake shoes. Just want to make sure this is right:

1 Brake Shoe Set, part # 18023301
2 Wheel Cylinder Kits, part # 18023305

Comes out to 116.52 for everything..

Do I need one Wheel Cylinder kit or two? I need to replace them both.

Or, I can get the parts from NAPA. Would it be the same quality or better? I know it's cheaper..

Left Wheel Cylinder, Rear - 28.99
Right Wheel Cylinder, Rear - 28.99
Wheel Cylinder Kit, Rear - 9.99
Rear Brake Shoes - 31.99

Total - 99.96

Do I need just one Wheel Cylinder Kit or two?

NONE! I think those Wheel Cylinder Kits are Only used if you are rebuilding your existing Wheel Cylinders. The only thing you need are the left and right wheel cylinders and the brake shoes. You might want to think about getting a new spring kit to replace all the old springs that are holding your brakes together now.
