A little searching will save you a lot of time and me a lot of work. I have quoted fender liners out a couple of times recently, and prices are going to be within 2% or so...

Also, I know there is a pic of a MkII in your avatar, but please, please tell me what you are working on. Not all MR2s are the same. Even if I assume it's a MkII, not all MkIIs are the same. Any information you can provide will generally save us both a lot of time and ensure you get the the correct parts for your particular car.
Let me know if you need something else, or give me a call when you are ready to order. Thanks!
