Slipper Cover Clamp Just Won't Fit...

[corsair]

Hi all,

I'm in the process of building the 2010 spec dex410, and I'm having fits with the fit of some of the parts.

However, with some workarounds, I'm still fine until now.
I'm totally stumped as to no matter how hard I tried, I cannot get the slipper cover clamp to fit in perfectly both sides of the holes. Initially I could never get it to go in. Either the pins itself has issues, or the molding quality of the plastic cover is really bad.

Anybody has any advice to how I can solve this problem? Picture is attached to show what I mean.
