Does the P70 work with Windows 8.1 ?
(I'm trying to get the latest hardware and OS I can get that does not include Windows 10)
I'd love to hear from anyone who has successfully installed it. Is there a guide anywhere about what drivers would need to be installed?
Does a standard Windows 8.1 install image work, or does the image need to be patched with the right drivers before installing?

First, I have never done it.
Second, the P70 was never sold with windows 8.1 so it might not get the kind of testing that Lenovo would do on win 7 or win 10.
Having said that, I would expect that you could download windows 8.1 from Microsoft here:
I would expect it to install, but be missing drivers. I am not sure, but I would expect that if you had a windows 10 Pro license on the P70 windows 8.1 pro would activate automatically. I looked through the drivers on the Lenovo site and the win 10 drivers used in the P70. If you install Thinkvantage System Update, it should fix things.

From looking at the download page at https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-p-series-laptops/thinkpad-..., it appears there are some drivers available for the ThinkPad P50 for the 64-bit version of Windows 8.1.
