Contact Phil at
http://www.rctankwars.com/Products.asp for all your HL/Mato tank needs. He's in the US so shipping is quick, he checks/tests the tanks he sends out and is easy to work with.
Myself and those at
http://www.rcuniverse.com/forum/tt.asp?forumid=369 order from him and I have only received great service from him.
Drop him an email and see if he has them in stock.
