Stan;
If I'm reading this correctly, you are planning to keep the bag from a Sinclair rest to put on a Farley rest and you are including the bag that comes with the Farley in your sale of the Sinclair rest? If that is the plan, it may not work out for you. The Farley rest bag basket (unless they changed it in recent times) is slightly smaller dimensionally and requires a "Farley" size bag (probably why Farley includes a bag with a new rest). Your standard size bag from the Sinclair rest will not fit. Protektor and Edgewood both make dedicated "Farley" rest bags.
