请帮忙翻译一下缺货的产品我公司会尽量想办法补齐,但有些产品已经不再生产,所以这些产品已经无法提供（见附件）,尽请谅解.产

Our company will try our best to replenish the lackingproducts, but we can't provide these products(refer to the attachment) which will no longer in production. At present, we don't have the product with the number 63004, but we have the product with the number 500MM; I wonder if we can use the 500MM to replace the 63004 product?
