[Farmall] F-20 Project Update - Sleeve Question

[Tony Pitts]

Hello,

After pretty much a 18 month hiatus, I am working on my F-20 Narrow again.  I have put an update up on my Restoration Story site at:

Now for my sleeve question.  Today I attempted to hone my sleeves and I found that one may be beyond repair.  This is the cylinder that was most corroded as you can see here (These are LARGE files, smaller versions are here (http://pg.photos.yahoo.com/ph/apittsworldnetattnet/album?.dir=989a):

After getting it loosened up, the piston out, and honing it looks like this.  You can still see some corrosion, and you can see a couple small divots in the sleeve wall.

Is this sleeve unusable?  If so, would I then want to replace all 4? Any other comments are welcome as well.

I'll have these photos up on my site soon as well.  I also just noticed I have some link problems on page one of the story that I will fix as well.  

Thanks a lot for your help,

Tony
