I bought a doubler off of another member. I was going to redrill the face of the front 203 to match my th400(Mine came from the factory with a np205) But thats going to add 4inch to the setup and its going in a 86 blazer and i want to keep the whole setup as short as possible. So im looking for a good th400 that has the adaptor and is setup for a np203. Im willing to trade mine for a np203 version. And if its to far away im going to have to have it shipped.
