So I'm searching to rebuild the KA in my 89 240. Only problem is that its bored 60 over. So the pistons I have are larger than what comes in the kit... Where can I get a kit without the pistons? I don't want to pay extra for something I'm not going to use. I plan on buying the pistons that would fit but I don't know how to look for them either, I'm a bit new at all this, so please, give helpful advice, don't just flame me.
