I talked to Trudesign in Colorado about widening my factory steel wheels today; they're a little cheaper than Stockton Wheel, quoting a price of $125 per wheel with powdercoating.
The wheels I want to get widened are 4.5", from a station wagon.
Looking at the info on the VClassics page, I see a recommendation of 3.5" inboard and 2.5" outboard. The current wheels measure about 3.25" from the back of the mounting surface (the side that touches the face of the brake drum)to the inside edge of the wheel rim, and 1.25" from the back of the mounting surface to the inside edge of the outer rim.
I'm thinking that I would be best off leaving the inboard dimension unaltered, and increasing the width solely from the outboard portion of the wheel.
I see that a 5.5" wheel is listed as suitable for 185/60 tires, which is what I want to install, so I should add 1" to the outboard dimension for 5.5", or perhaps 1.25", just to be safe, which would give me a wheel width of 5.75".

Does it seem like I'm on the right track? Any suggestions?

I don't care to do any prep work (cutting) myself, as I have neither the tools or the experience to attempt such a task.

Incidentally, the 4.5" factory rims (oval holes) weigh 18.7 lbs. with no tires installed; 2.7 lbs. more than the Superlite wheels IPD are selling.
