An experience toyota mechanic tells me that he's had as much trouble with toyota clutch cylinders than with parts store crap. So : ~$120 from 1sttoyotaparts.com (for both) or ~$60 from advance - worth it or no?

Usually I would go with the toyota, but apparently since the seals are the problem, and the design has been improved even at the parts stores, there isn't much difference.

 

i've never had a problem using aftermarket stuff.
