Thanks guys.
Lawrence, I managed to rip off one from each side and turn them around. Since I had allready cut them down to fit the track, they don't look good, but I hope I will be able to cover them up somehow.
Here is to lower hull finished.
I added the antenna from stretched sprue.
And here it is, ready for paint.
The barrel is like that, because I had a hard time fitting the small part to the end of the barrel so I put it on a dremel and started sanding but I accidentallly broke the barrel.

It is now OK and the putty has been sanded down.
