Modern Iowa class questions.....

I got my 1/350 NJ today and looking at the deck pieces I see a problem. They have the "flight deck" molded into the aft deck section, and as the Iowa's wasnt like New Jersey's how would I go about changing it from the New Jersey deck:

To the Iowa deck:

any ideas???

Also, does anyone know what the best PE set to use for this kit is? Looks like the GMM set would be best, anywhere got it at discount prices??

Thanks! -Abram
