Alright guys, I took care of this on my car. I ended up drilling it out because I couldn't find the union fitting. Here are my pics:
This is where it is located. You have to remove the rear half of the fender liner in the front left (front, driver's side) wheel well. Once you remove that, you will see this. The restrictor block is in the right side of the shot, in the bottom rear of the wheel well:
This is what the actual restrictor block looks like:

Once you remove the clutch lines and the mounting bolt in the center, you can pull it off the car. Here is a shot of the restriction:
I drilled it out with a 5/32" (4mm) drill bit. There isn't much to have to drill through. Basically, as soon as the bit started cutting, it fell through. Here is a shot of it drilled out:
Then everything gets bolted back together the same way as it came out of the car. Pretty simple.
After refilling and bleeding the clutch, I went out for a quick test drive, and I gotta say, it made a difference! It's hard to tell how much quicker it shifts since it's 40 degrees out, so I don't have any grip from my tires. On high rpm shifts, it either wheelspins, or traction control comes in and softens the shift. But the clutch feel improved, and I do think that helped remove the clutch delay. I'm excited to test this when it's warmer out.
