I was reading your question and I'm not quite sure what you are trying to ask but anyways. I got a TRD
clutch and it was fairly expencive but not compare to the stock one, which is 220$, I think. Only 80$ over the stock clutch price that the dealershop quoted me. The TRD
clutch was quoted at 450$ or 420$, don't remember now.I got it at this place http://www.camelbacktoyotaparts.com/prodlist.asp?NodeID=71415&TopID=70001
The good thing is I didn't have to pay taxes on it since I'm in CA and the dealership is in AZ.
Regarding the install the dealership quoted me 750$ for the install with everything out the door (with no money left in your pocket) independent shops would install it for a bit less but I got lucky I'm going through a friend and I got it for 400$ So my suggestion shop around the shops maybe pull over couple of boys with riceburners ask them around maybe they could suggest a place where you can get it done for cheaper but I think you won't be able to get for less than 600$ depends on where you live obviously but it's the labor that kills you. Hell, you can even drive to Mexico to install it
