They don't really make them..best bet is to pick up a used motor out of a 93-97 Probe GT, Mx6 LS, Millenia L (a couple things will have to be swapped from your old motor), 626 V6.
Actually, being in STL, there are a couple of close friends of mine that usually have KLs for sale. They usually post them on craigslist. I have bought a couple from them with great success.
