Dear Supansa,
regarding this drawing p/n 623920-23 I checked it and you are right. There is wrong qty of dimension 8,0mm for cutouts. There should be dim 8,0mm 2PL instead of 6PL and there is missing dim 7,0mm 4PL for cutouts. Please make in accordance with my sketch below. The new RL is created by me and will be forwarded to other processing for my colleague.
