They are not widened steelies they are brand new custom built steelies. They are one-offs built to my specs.
There is a place out in Cali that has these rims available in several widths and then for a small fee they will weld in the face in any custom backspacing you want.
These wheels I have are 15x8"
Fronts are 5.25" backspacing or about 18mm offset
Rears are 4.75" backspacing or about 5mm offset.
I took measurements and retook measurements about 5 times before I ordered because I wanted these things to fit perfect. I did it, the rims opke out from the fenders just a bit then the stock tires were stretched on and they tuck back into the fenders, it's sweet.
www.custombuiltsteelwheels.com is where you can get them. They are the WS60 model. They come in black primer only and rust almost instantly so you will need to paint or powdercost them.
With the custom offset they were $85 each and $440 shipped to my house.
