Dear friends Dytech schedules to deliver 80 sets of SUM001, 002, 003, 150 SUM004C and 114 SUM005. I attached the drawings of the two parts. Please measure the received parts and compare with the drawings. If not consistent, pls let me know. We have some SUM004A in stock already and it looks similar to SUM004C. Pls do NOT mix 004C with 004A. Also we need to check if 004C can assemble with other parts, not only with the 80 sets but also with about 70 sets chassis box we ordered last time. If the colour difference between the new arrived parts and parts ordered last time is very obvious, please let me know. The manager of the client changed one more time, since we confirmed the order. So I do everything I can to make sure the goods will be accepted without problem, even it means higher cost and more time. Otherwise, we will not receive any further order from the client. Thanks Eric
