N.O.S slowboy water pump adapters for the 4G64 Evo swap.
These are a massive 1/8 thick to prevent warping and help sealing. All other brands skimp and make them from half the thickness.
For use with Evo 7/8/9 water pump on a 4G64 bottom end.
These were built by slowboy Racing and we happened to get a hold of some that were sitting on another vendors shelf.
