We are trying to replace a "Del Mar Eng, Long Beach, CA tandem roller. It has identical dimensions to Swisco #
81-052, so we bought two assys from you. However, two differences prevent using your assys.
1) see photos of original -yours has countersunk and threaded mounting holes on top; the original is flat plate, 17/64" holes only. Our very short mounting bolts screw into threaded door plate, thus will not work with Swisco threaded & dimpled mounting holes.
2) Original has flat sides, Swisco has two "ledges" that prevent fitting through our door vinyl slot.
Do you have an assy matching our original assy? Or can you modify your processes to fab two parts we need?
Many Thanks
