My 88 4Runner has about 200K miles and I have owned it for the last 20K. I was thinking it might be a good idea to replace the timeing belt, oil pump and water pump. Having head many good things about Engnbldr I called and ordered the belt and oil pump, I was told they did not carry the water pump. I was expecting to receive Aisin parts or at least good quality Japanese parts. What I got was Rock's. Not stones but D & J Rock products. Does anyone have any experience with Rock parts. I've never heard of them.

Thanks for your help.
