just looked into the below further. It seems that the way the wood pins and aluminium caps have been packed this batch is very misleading. Its easy to not see them as its just in the white foam wrap. The pdf attached will give you a better picture. The packers explained that they did not want to scratch the surface of the back panel and hence they placed it on the side. I will improve this part from our end for all future shipments. Please do mention this point to the persons unpacking and assembling the units when as its easy to mix them up with the foam wrap cover and cast it away.
You will have the spare sets by Monday. I apologize for the inconvenience.
