Thanks for writing in. Start by reviewing either our 39-031 & 39-032, or our 39-155 & 39-156. Look over the dimensions of both sets of operators to see which is a better match for what you need. If your old stud brackets are undamaged you should be able to reuse them; otherwise, see our 39-509 and 39-510. |
