What's more difficult to replace than the AOS with the engine in is the coolant tank. That's a real PITA to do and 100 times easier with the engine out. Just a suggestion, if you haven't already addressed it.

Pelican has that, too. Yeah, it's pricey, but yours is 25 years old, unless it has been changed already. Is it white or yellow? If it's yellow, recommend changing it. If you could only do one, I'd do the tank because in comparison, the AOS is much easier to do with the engine in, plus the AOS won't leave you stranded if it goes bad.
