They must have been out of stock when I ordered then.
BTW, get some 'water wetter', Redline makes a good one, and run it mixed in the radiator. It really improves the heat flow. I use it in my BMW in the summer when I'm using the A/C and it keeps the coolant about 10 degrees cooler in traffic. I put it in my truck too. It's basically a detergent that overcomes the surface tension of the antifreeze and it conducts heat better.
