Build the super structure back from scratch if you can. I'm building the one from harbor models and I must say that the only thing I plan on using from the kit is the upper cabin house. And I will still have to modifie it just to get it right. The rest is not of usable quality. The plastic blow molded part has a lot of deformed areas that really disipointed me. So just use what you have left as a pattern and enjoy the out come.

Just my 2 cents worth.
