what is a canton tank

I just put one in mine, it's just an expansion tank but it's not leak prone like the plastic jug is, plus it looks a lot better than an ugly yellowed plastic one. That alone makes it worth getting, to me. It accepts the stock coolant sensor assembly, and can be polished for extra bling under the hood. Pictures of it in my gallery.

I too say keep the stock jug, if you want it to be a 100% original Triple White. The Canton bolts right into the factory location so no modifying should be necessary.
