Yep, I'd just get the 30 spline longs, I remember when redline offroad in seattle came out with the first eliminator then it was bought out by randys.
You are young to the Toyota lineage my son
Warn had a birf-eliminator kit many moons ago, and even it was purchased from some other company at the time as I recall. They cancelled it along with many of their other Black Diamond products and the rights to said products were later sold to other companies (Redline might have ended up with the Warn setup?). This all occured long before Randy popped into the scene. I've got a couple of product cut-away demos of the Warn Birf-eliminatror and FF kits.. neato, but they never went too far. There are still some old Cruiser running around with them.
In addition, companies here in SLC were effectively doing "Birf-Eliminators" back in the 80's (ie: Advanced 4WD, Rocky Mountain Axle-Charles, etc). However the neat thing then was to use D44 outers (knuckles and all) on the Toyota housings. I still see customers running them from time to time, not a bad option when there were zero birf upgrades and D60's were considered overkill. Now that Longs, et all are out, I see no reason to run anything but. There are a coupld other limitations of the Toyota style axle, but none have gone un-addressed... If your going to go as far as to "eliminate" birfs, you might as well eliminate the axle and go D60, etc.
Here is an old Warn kit:
