Hmmm, after deglazing the cylinders will you be over the limit? If I'm not mistaken, the spec is the piston to bore clearance. If your used pistons are worn, that wear adds to the clearance. If I'm reading your chart correctly it looks like cylinder 3 is over the spec for out-of-round (III 1A and 1B difference is 0.0020).All of that said if you deglaze and rering it, you'll probably get a lot more miles out of it.
General question regarding piston sizing. I've looked at new pistons on many websites and it seems I can find the Standard size, then 77.00, and 77.50. Are pistons no longer made that would fit into the Repair Stage 1 range of 76.73-76.75?

So you are saying even with measurements in cylinders 3 & 4 that are above the wear limit and at a minimum cylinder 3 is out-of-round, you think it would work to deglaze the cylinders and install new rings? How many miles would you guess before it would have to be bored up? How likely would this come with immediate oil consumption and blow-by? I'm trying to get a sense of what doing this would be like vs having the block bored up a size.
Pictures and video of broken IM shaft, and outer bearing.https://drive.google.com/open?id=1QLvWKthNRVxWEmJ8jfw8S8f_A57kM4vaI have two candidates for replacement. the gears are different sizes. I did read that the gears can be removed and pressed on. I've read how the thickness of the shaft changed from the 1.5 to1.6 engine as the 1.6 needed more room for the longer stroke. Also how the 1.5 oil pump was shorter and the 1.5 vacuum pump slot was lower to match. Anyone know, or know of a thread somewhere that explains the gear size difference? I'll probably throw the longer geared shaft in at some point and see if it works or not.https://drive.google.com/open?id=1ypifmkWXvy8TajhUN5WChK0Coi4_UFxo
