Constraints issue with Ram in assembly
Accepted answer

After downloading the files you just posted, it seem there are still a half dozen parts missing. There is not enough to work with.
You MUST learn to use "Pack and Go". An assembly (IAM) is nothing more than a place for parts and other assemblies to come together and receive constraints relative to each other. Assembly files never have any 3D geometry.
IF YOU DO NOT INCLUDE ALL THE ASSOCIATED PART AND ASSEMBLY FILES, AN ASSEMBLY FILE IS TOTALLY USELESS.
I'm sorry I cannot help you with an incomplete assembly. Good luck.
Again, Please learn to use "Pack and Go".
