HELPPPP!!!!!!!!

I am planning to build a dio including a shermanA-1 withe a jeep and maybe a knocked out panther or tiger! i am wondering if any one els has done one like this? if so some pics would be nice to give me some ideas.
Also i need a place where i can get conversion parts and interiors for armored vehiculs.

For the Sherman, some of the best conversion pieces come from Chesapeake Model Design http://www.chesapeakemodels.com/ . The best interior for a Sherman that I have used comes from Tank Workshop, they are now being sold through Tiger Models www.tigermodels.com

Many aftermarket parts are available through other sources … what are you intending on changing?
