Ok guys, I orderd 4 of the Mouser Part Number 587-341-040 Mfg # 341-040-520-202 $3.34 each. 40P SOLDER TAIL RoHS non-compliant EDAC Cardedge & Backplane Connectors. They fit perfectly. Only difference is you don't get the big grounding clamps the screw into the mounting holes. Not really a problem for my purposes. Have at'm Tim
