Axle change out

So ive been a scrolling and I'm sure there is a thread on here that can help me out. If any one can find or has a link to this id be a help.

Question is can I just swap axle spindles out of my 2000 RWD Tundra with the axle spindle assemblies from an 01 Sequoia directly if the rear gearing is the same? Or are the differnt spline cuts?

Benefits, rear disc brakes and parking break assembly for cheap, yet still being factory. Also LimDiff install. So 2 wheel peel lol.

A preemptive thank you for the info.

 

Discs? I thought rear discs had a dependency on the rear axle housing as well? I know the axle housing for DC/Sequoia is diff't width than AC/RC pickups, not sure about the spindles though. I would assume if housing width is different, spindles would need to be also, but I can think of some cases where that could be false. Anyway, never had to touch it here, so don't mind me. There's a better voice to answer the Q. @des2mtn has upgraded to rear discs, but I never looked into how.
