Agreed. I talked with my local dealer and he said they would come out Feb 2025. I held my Land Cruiser spot and added my name to the “list” for the 4Runner.
If there’s a manual option for the 4Runner then it’s a done deal for me!
Driveshaft type just depends on your angles at the flanges. If you can post those up with a digital angle finder we can give you an answer pretty quickly.
4 degrees of caster should work fine. 6 might be better with the lift and tire size you’re running.
