I'm not sure I understand the first part but I'll try -
As I am sure you know Lasco closed down last Sunday. However, there are still an outstanding 928pcs of PD6810, which have not yet been shipped. We would like to switch them to Texaco who are able to keep to our schedule to ship before end of March as per our commitment. Please confirm your acceptance by return.
If i am wrong about the first sentence, let me know what you meant and I'll rewrite it.
