Ok, build up the outer edge 1/8 inch so the ring will fit. 3/8" wide. I have no idea what type of steel, whatever's common for an aftermarket blow proof wheel, sliced off of a bar is my guess.
I would add the weld would not be within 1-1/2" of the clutch face. I am curious, how did you get a mismatched flywheel and ring gear that is off by 1/4" on the OD? Short answer, 66-69 Hemi wheel, direct drive starter, ring is on the clutch side, all others are on the block side, 318 to 440. I guess they machined the back side smaller so idiots wouldn't put the ring on the wrong side, or maybe for bendix clearance? One of the many "bright" ideas from Chrysler. The only reason I'm pursuing this is that its a brand new, premium steel, made in the 60s- 70s USA product, not some new Chinese stuff.

If it's a full perimeter kind of thing I'd be tempted to make a ring from flat stock and use a few short welds to hold it to the flywheel. That would induce far less heat and stress than a full perimeter weld.
We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.

I bet they even make flywheels that actually fit
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Make a ring the proper interference size to fit your flywheel and ring gear, then heat it and place it, let it shrink, then heat the ring gear, place it and let it shrink, been there done that!!
You got it, ta da. Exactly what I been thinking all day, and will do, 1/8 X 1/2 rolled and welded in a circle ever so slightly bigger then the inside of the ring gear, heat the ring to fit the spacer then the same on the wheel, tig weld a few spots for good measure, done! Test it to 10,000 rpm a couple times, if it stays on, run it. A simple fix for a simple item, it's not the space shuttle going to Mars. Thank you all for your answers, the good and not so good.
