I'm also stockpiling parts for much of the same maintenance on my 4WD - the difference being I have zero maintenance records from the PO and it's not my DD or even close to it so I haven't noticed any high coolant temps, yet.

Mine had black Husky floor mats in it when I bought it, very similar to weathertech in style and fit albeit thinner. I swapped them out for the tan weathertechs from my 2WD. Thankfully the carpet in my rig is also in excellent shape thanks to the POs Husky mats.

I'm curious about the Koyo radiator (I bought a Denso from Longo Toyota) and I too have a 5-speed and don't need the trans cooler...

I've been waiting to do the rad swap and flush, and will also change from green juice to red juice and eliminate the rear heater & core in the process. I don't see myself using it much in SoCal. I was waiting for the timing belt replacement as not to have to drain the system twice and I haven't felt rushed to do that job yet. I've been focused on suspension work and ancillary electrical projects.
