Whoa... MIP makes the best CVDs in the industry. They are the creators of the CVD.

Your first mistake was trying to reverse engineer them. If you had an assembly issue, why did you keep putting them together? Usually if something doesn't go together right, I put it down and call the MFG instead of continuing assembly. I guess I am giving MIP benefit of the doubt here and leaning towards operator error. I am not saying they are perfect, and maybe you got a bad CVD or wrong part, but you should have handled it with them before putting them on the truck.
