WiMiU Artemis SLS Transport Rocket Building Kit,NA.SA Saturn V Space Launch System Ship Toy,Artemis Model Blocks Set, Outer for Kids Teens, New 2022 (437 PCS) (C9159-99455)

This model is very nice at about 8 inches high. The pieces are in about 5 bags and come in a resealable larger package. The only drawback is that the instructions do not come with the model. You have to go to a website to get them and I could never get it to work. I found the directions on another website so you can find the directions for this model on the web.

I am trying to build this model but these two parts don't fit. How can I get the right parts that fit? I have never had this problem ever. Thank you.
