Dave,that picture was of the bottom curve as you know but mine were out at the top corners too!
I'd be suprised if your glass was all original,if so chances are the glass would at least be showing its age,I would at least expect some de-lamination or yellowing.
Bottom line is I recut my windshields after making templates from 3/8" Plywood.
What I did discover was the left hand (drivers side) aperature was 'tweaked' due to some accident trauma in the past so my left glass is ever so slightly different from the right,but not so bad as to show.
I do have a slight advantage as I do this for a living.
They're a dang sight better now,but even then I still sealed them well.
If yours aren't as bad as mine were I would persevere with the sealer,unless you want to go down the new glass route.
