Hi there Airman,
Thanks for responding to my post. I'm looking for a metal gear rack with dimensions of about 1 ft long, 1/2 inch high, 3/8 inch wide. The gear teeth could be any size it does not matter, and the dimensions of the rack do not have to be exactly the same as what I've just listed. Also the rack and pinion gear could be made of any metal. Thanks again for replying.
