Differential, transfer, transmission, and engine drain plug dimensions and magnets.

2004 LX470.

I've seen some aftermarket drain plugs with magnets for capturing ferromagnetic contaminants. Seems like at least some might come with one stock. Can anyone verify if any of these five plugs have a magnet from the factory?

For the ones that don't, if anyone happens to have the plug on hand and could provide some pictures and measurements of the inner end of the plug, I'd like to add a magnet this coming fluid change and post back with the results on the next one. Maybe not the transmission plug, since I don't imagine I'd do a fluid change there without just pulling the pan.

If I had to guess from images of the part numbers below, it looks like the transmission and engine plugs don't have magnets, while the other three probably do.

9034118040 - Rear Differential
9034118035 - Front Differential
9034118057 - Transfer
9034110011 - Transmission
9034112023 - Engine

Good reminder on the washers! I'll probably end up adding my own magnets though. All the ones I've seen being sold seem like they have ceramic magnets. I wanted to try putting in some high temperature neodymiums.
