Help choosing a stand for my 75 gallon tank

I am moving and can't take the stand my tank is currently on as it was in the house when I moved here and doesn't belong to me. My question is do you think my new stand option will hold it?

Currently the stand that it is on is 17 inches by 60 inches. As you know a 75 gallon is 18 inches by 48 inches, so it does hang off about a inch or so. I know the stand is well over 200 pounds. I also have about 50 lbs of slate in there. Here is a picture of the current stand the tank is on:


Now this is the stand in question. It is a dresser stand that holds a huge mirror. I was wondering if this could possibly hold it. This is 18 inches by 65 inches. Not sure how much it weighs my guess is between 100-200 pounds. Excuse the mess as it is used for hair and make-up. I couldn't get all of it in the camera, but I got most of it. Here it is:

The first thing is not a dresser. I'm actually not sure what it is lol. The first thing is huge and isn't hollow on the inside. I had it sitting on the thing in the first picture for almost a year. Also, before the whole back of the tank was slate. So I know the slate added a whole 100+ pounds. Right now 175 is too much for me as it costs a lot to move. Also, I moving in a week.

It used to look something like this:


Then it slowly became this now:


Now it's the first picture I posted. I am going to skip out on the dresser though. Now I am in search of a stand.

Do you know where I can find an Iron one? As far a store or place that might carry them. I really don't care if it's wood or iron.
