The two pieces you are talking about are the missile pod sides. The ones with the indention are for the
LC and
HB, while the smooth sided ones are for the missiles. They messed up the instructions and labeled them the same number.
Here is what I did to magnetize them -
If you go to my gallery I left an explanation of what magnets I used and such. Probably over kill in most peoples eyes, but I prefer the ability to use all the options on a model. You never know what will change when they come out with a new rule book.
I'm heading to work, but if you have any questions, I'll check back later today, or you can
PM me.
Hope this helps out.
