Would the ones for the 2UZ fit the 03-04 v8 models or is the pipe routing different? URD doesn't carry the ones for 4th gen 4runners but they have the one for 1st gen Tundras.
Every post I've read here and across a few other boards has confirmed that any Tundra header will not fit our 03-04 4runners. These headers are made in small batches here and there about 2-3 months apart.
