My cabinet slides are rough. The no. UNIGRASS 6600 is stamped on the drawer side. Total length of the slide on the drawer is 22 1/2" 1 " wide, with a small lip under the edge of the drawer. A 3/4" roller is on the back corner. The inside cabinet rails are 23" long and attached to the cabinet face trim with 1 screw and slip over a bracket mounted in the back of the cabinet. I see part numbers like 6600/570 DML 01225-09 and 6600/570 DMR 01248-09 for extended brackets or 6600/570 01510-05 for a set of STD slides. Please tell me the cost of the set and the cost of the extended slides. Thanks.
