You can buy a piece one square foot of normalized 4130 from Wicks and they will cut it the way you need it. Ask for Keith when you order. He's the one that will cut it. He cut my complete set. ?No extra charge. Then I had my son drill the holes on his CNC .

Then yes, I'd just make a new set of WAFs also.? Although you can stress relieve 4130 after welding with a torch, to be sure it's as good as new 4130 plate, you need a "certified" welder, checked for incomplete penetration with radiographic inspection.? New holes in new material is the way I'd do probably do it. ? It's a lot easier and cheaper. But just to throw another curve ball, given the amount of "extra" material around those holes, if the next larger diameter bolt would work, there's always match drilling to use the next size larger bolt, or even two sizes.? Now that I think about it, that's exactly what I'd do if it were mine.
