More Case 450B questions

1)My adjuster cylinders do not look really bad. Why can I not just add about 1 inch to the length of the proper adjuster rod so it sets deeper in the cylinder where pits are less likely? I made a new rod last week and have 2" stock to redo if this is a feasible idea.
2)I have all 4 adjuster yoke mounting bolts broken in the front roller mount. I assume I can just flip front roller around and use other side?
3)I have one tilt cylinder that has a nice patch of rust where there should be chrome. Any way to repair without having turned and chromed? Remember, this is for farm use only. I have already seen my budget go out the window and I already have the seal kit. A little seepage is OK.

BTW - local Case dealer will come and get and rebuild engine, complete rebuild including removal and cleaning and head work for about $800 labor. I am seriouly debating as I do not know the history of this engine and based on what I have found elsewhere, I doubt original owner maintained it like it should have been. Before I commit, I intend to remove injectors and get tested. I will keep you posted.

Thanks as always for the advice.
