Got the largest Napa had then returned it. LOL! Wanted way too much $. I couldn't find one close anywhere. I still thing I had to wrap some masking tape around it to make whatever I had larger. Still need to go out and get the proper one.
If you own a welder you can make your own. Buy a high grade bolt with 1/2 inch head on it and then weld another piece of worthy metal to the end of that bolt to create a handle.
Or be cheap and use the bolt idea plus some vice grips.
