CPS: Anticipatory Replacement Or Wait for Failure?

CPS: Anticipatory Replacement Or Wait for Failure?
I have an 01 D2 with ~170k on the clock. I just purchased the truck recently and have been catching up on the major service items and was wondering whether I should go ahead and replace the crankshaft position sensor. From what I can gather, it's not a repair that you can realistically make roadside, due to the high temps among other factors.
I don't know how long the part typically lasts but it seems like it's an inevitable point of failure - presumably it's been replaced at some point, but I can't be sure. It's only like $40 for the part, so it seems like cheap insurance.
I did some searching but couldn't find much on the general consensus here - do you guys recommend replacing it proactively or taking a "if it's not broke don't fix it" approach? How long do the parts typically last?

Not because of the unknown sensor duration, but for the action of getting hands and tools in there with the risk of dislodging/damaging some wire/connector that can be for something else; I would not touch something that works fine. Prefer the approach "if it works, do not touch it"
It's just in a tight spot, but not a big deal to replace.

Failure cause is heat soak from the exhaust manifolds, LR put a cover over it and painted the cover silver to help. It does help a bit but not as much as is needed. I wrap my covers in aluminum foil and/or put an aluminum heat shield between the cps and exhaust manifold, helps tremendously. I had one going out, would not start hot. Put the heat shield on it and now she works fine for the last 30k.
