Hi all -
I'm continuing on with my 1949 styled Model A John Deere restore journey and am now a little frightened with the rust I encountered in the cylinders.
What started as simply replacing a rear wheel bearing and firing up a beloved tractor from my childhood - I foolishly figured to be a couple weeks worth of work.... has now ballooned into a full rebuild. AHHHH!
I've posted some photos of the cylinder head and engine block here so that you can get an idea of the rust I have questions about:

I've been using a "google site" to post photos of the project for interested family members to view. You can see the rest of the photos here if you are curious about other aspects:

But the questions I have now are these:
I'm sure a rebore is in my future... but could the rust damage be so bad that even a rebore is not an option?
Is it possible to put sleeves into this type of engine? I have not seen it mentioned online anywhere.
I'm hoping to avoid buying an overboard piston kit.. they are crazy expensive. Yeiks.
Also, unrelated to the engine... are there standard bearings that will cross-reference to the rear wheel bearings on this tractor? According to this site: http://www.yoyopart.com/oem/14319690/johndeere-jd7392.html - the JD7392 wheel bearing looks to cross reference to a TIMKEN 33275 - which is readily available.
And related to the bearing.... the race part that is on the axle shaft... is sort of loose - so it rotates, but I don't see how it can be taken off without MUCH force. Is that normal? And if so - how do I remove it?
<whew!> Sorry about so many questions guys! I really appreciate any advice and comments!
