Headache Rack for 2004 Frontier XE

Hi,

Looking for a Headache Rack for my new 2004 Frontier.

Shops I've checked with so far, scratch their heads when I say Nissan, seems they only stock Domestic and occasionally for Toy Tacomas.

Purpose - place to mount a couple of Amateur Radio Antennas, and perhaps to aid in transporting an occasional Canoe or other small boat.

Would like to look and touch before I buy, so stores in the Houston or Austin Area would be ideal (I live halfway between both)

Mail order could be acceptable if I can see pictures of the Rack on a Frontier and they don't charge an arm and a leg for shipping!

Thanks in advance,
Ben
