I have searched this and coulndn't find a straight answer for either. How difficult is it to remove the but-pin on Classics Megs? Although I've seen it done I couldn't find any detail on the process. And two: which end on the pins on Ops lower arms (the lowest pins for attaching the vehicle panels) is the textured end? Again, a search proved un-successful for a play-by-play of the process. I'm planning on doing this Tonight, so I can start an new project. Thanks in advance.
