8.75 poor man's locker-

I've never seen one of those.
How does it work?
I'm guessing the axles are splined into it?
If so, boy, they can't be hanging on by much.....

I drove a spool once with 295 Coopers. From one weekend to the next, that cured me. Tight circles seemed like each tire was trying to rip itself apart from the inside.
I might still have that spool!, likely with 4.88s on it.
