DNS INDUSTRIES 12 INSIDE PULL - 1400 SERIES (SILVER) REPLACEMENT

I have 2 handles I would like to replace....... Lasted 18+ years.... Home Depot, Lowes and or Ace does not carry the correct size.....lock latch to in different location and door would not modification for them to work......Do you have the handles in stock and what would be the cost / shipping fee?........Also if you do have them in stock, I'll add the information to our neighborhood web site......Community has about 600 homes and each house has 2 patio doors........Homes are 8 to 25 years old and all that I have seen have your handles.........
