Dear Mr. Dunker
We are now confronted with a major problem because (it was) one of the bushings (have been) needs rebuilding while on the other hand, we are making to preparations for sending another bushing as mentioned (which have been also said) in our previous e-mail.
Considering the fact that we do not have any bushing in reserve (of) stock, we request (ask) you to kindly (that you can) replace a new bushing from your stock with our old bushing. We hereby make it clear that we will pay the differential amount (of difference) mostly representing the cost of alloy and other charges. Your cooperation in this matter will help us (has caused we) to save rebuilding time and place us (for access) in a safe situation. This means that whenever we send a bushing for rebuilding, we receive a new one from you in replacement at the same time.
We hope that you will appreciate our situation and (that you can) help us by replacing a (your) new bushing against (with) our old one (bushing).
Meanwhile we have six pieces 1400 nozzle bushings that (they) need rebuilding at monthly intervals.
Please keep us informed about your viewpoints (in) at the soonest possible time.
Please delete the words in the brackets.
