evinrude tilt/trim overhaul ('77)

Here's a pictorial of my '77 tilt/trim unit:

I haven't seen anything like I need.

I'm thinking of taking the cyliners out. I can diss***emble and re***emble OK.

1 Is there a set of O'rings, gaskets, and whatever trimmings it takes to do a complete cylinder overhaul???

2. On these, is there anything I should look for in damage inside the cylinder or the rod? Hopefully not. I'd like for it to just be a cylinder overhaul using small parts.
