2.6 Liter Mitsubishi engine

I have a 2.6 L Mitsubishi engine with a Mikuni carburetor. I would like to know if anyone has found a generic replacement carburetor for this Mikuni carburetor that I could use to replace the original Mikuni carburetor that came with this 2.6 Liter Mitsubishi engine on my 1985 2.6 Liter Dodge caravan.
