I think I've said this 14 times in this thread already, but the attention to detail here is incredible. Kind of reminds me of taking apart my broken macbook in college and being amazed that the inside was beautiful too.

I had no idea this was a thing. THANK YOU
haha thanks man, appreciate it
I'm sure you're familiar with the overseas parts companies at this point but for anyone else reading, here's a run down of what I've learned in my time buying parts. I'm not an expert like some people here on Mud but I have bought enough parts that some people from Toyota USA wanted to pick my brain recently on how to make their parts site better... haha it was actually an interesting conversation. long story.
Anyway -
Partsouq - Nice to have the EPC to find parts. Things get shipped surprisingly quick, often faster than US dealers. They don't have as much in stock as other companies, but if they say they have it in stock, it's actually in stock.
Amayama - Also nice to have the EPC. They seem to have a lot more random/obscure parts but their system often tells you an item can be ordered, only to be disappointed in a week when they get back to you and say it's actually not available.
Impex - No EPC so you have to know your part number. Allegedly just a couple guys working out of a garage in Japan ordering parts from Toyota. The price difference is impressive - I priced out a $400 Amayama/Partsouq order and bought it through Impex for $250 just yesterday. The con is that they're often much slower than Partsouq. Sometimes you'll be waiting around for parts for weeks
Some other Impex-like sites are MegaZip and Yoshi Parts. Unfortunately I don't think there are any magic warehouses full of exotic forgotten parts - everyone is ordering straight from Toyota so they're all pretty similar at the end of the day.
And then of course there's Dave at Japan4x4. I buy obscure stuff from him all the time. Super helpful guy. Goes above and beyond to find what you need and it's nice to be able to talk things over with a human (and native english speaker)
And this site is a nice resource:
