15" COOL FLEX over flow tank for sale

i have a 15 " COOL FLEX over flow tank for sale. These Ribbed Overflow Tanks are 100% Billet Aluminum! Includes fully adustable mounting brackets for ease of installation. needs a little more cleaning, but other wise it is in good shape. wouldnt hold enough water for my every day driver truck, so i put the stock tank back on. i paid about 90.00 plus 20.00 shipping about 5 mo. ago, will take 50.00 for it. you can let me know by e-mail. thanks, mike
