oh man, this is great. I always enjoy following your builds, and now you are building a 4th gen (which I have as well).
please do a HID retro next, so i can get some ideas and maybe even copy you...! I was the one that emailed you concerning your new rotational mounting methods on HIDplanet a few months back. I have some RX330 lined out for my retro, just trying to think of the best way to solidly mount them.
Thanks for following along! What year is your 4R? Mounting will depend on what style of headlights your running. Our "new method" was simply a way we were able to set the rotational alignment quickly in non-drop in projector retrofits. We were using an adjustable jig and a construction laser. Took a while to get everything working so for one set, such as your own, I would say just proceed with the known and tedious method of checking it over and over again.
UPDATE
Have had a little time over the last couple weeks to tinker on the 4Runner. Still waiting for parts to show up but it seems like some of the most crucial components are still not here and holding me up. Suspension, brake lines, bump stops, links are all here... but I am waiitng on backordered MetalTech rear coils and Total Chaos UCA's. I wish one of them would land so I could at least start turning wrenches on one side of the suspension! Oh well, should be making a trip down to MT in a couple weeks at which point I'm hoping to have everything I need. Front bumper is even down there waiting, but I'll have more info on that unto itself when I install it.
Like I said at the beginning, I would be taking the build slow....(lol) parts have been piling up but RickRunner is still stock basically. Using this "down time" to hit some of the finer details before I am able to tear into it.
We had a chinook blow through Calgary and saw temperatures of +11 degrees C. Warm enough to paint

I cleaned up the undercarriage a little, dropped the spare tire and applied some rust prevention primer to all the frame welds, then followed it up with a coat of gloss black chassis paint. Really happy with the results. Hopefully this helps keep the rust away and allows me to battle it one winter at a time. I still can't believe how clean this 4Runner is:

Finished the 3M carbon wrap on all 4 of the door panels. Nice to have no more "fake marble" trim:

Pulled apart the dash for the 20th time - getting pretty fast at tearing the console apart! haha Installed a RAM mount for my phone/tablet and also a BlueSea USB port to charge the phone or tablet while in use.

RAM mount removed for the DD look:

Random shot. Love the 4th Gen guages, and I never get tired of that low mileage! haha

Starting to think about cargo management as well. Have a couple good sketches now for the rear storage/sleep platform and very excited to get started on it in the spring. In the meantime just organizing my gear a little better and appreciating things like this BlueRidge Overland visor MOLLE setup:

That's all for now. Might attempt the front seat mod tomorrow or start on my projector retrofit. The LS430 projectors are gunna look right at home in the pre 05' housings. Stoked for proper light output again, missing the Tundra headlights big time!
