Just put Ravenol 75W in my 13 LC a few weeks ago. No issues.
Did you use the Ravenol 75W Manual Transmission Fluid or the Ravenol 75W-90 gear oil?
 
I knew this was the thread with the part no.... MUD search is a pain.

Here are some photos though.

where do you buy "strong enough" magnets... this is all I was able to find via google: TOYOTA/LEXUS NISSAN/ INFINITI

what do you recommend?

I wanted to pass along a data point about these specific plugs. Magnet is incredibly strong. The front differential drain plug is not cut appropriately and will not fit. The email/contact responses are sporadic at best, but consistently lacking. The rear drain plug sized and cut appropriately. Just a heads up as I'm stuck with a plug I cannot use and cannot get replaced due to no replies to multiple emails.
