Thanks to the pity the next guy body session, I'm whittl'n away. From here? I've set up a 4 point measurement. Striker to door opening (hole don't laugh) 46" & 3/16. I'm off by 2 16's-1/8'' that's the span of the total door opening. For the he other 3 points, I used the distance from plate to 1st screw hole - compass. The distance between 2 panel holes - compass & the distance between two seam lines - compass / off by 1/16" on the same seam that brings it away explaining the larger door opening.
