Default Outer spindle ABS and nonABS

Just noticed the rear outer axle spindles have an ABS ring on them. Is the ring pressed on or part of the spindle? Are 84/85 spindles compatible with an ABS car?

Spindles are part #'d as '84 - '85 and '86 - '87. I don't have any '86 - '87 spindles or the earlier to check but I would say the non - ABS could not be used with the later '86 - '87. There was an inner seal for the '84 - '85 that isn't used on the ABS units and I expect that sealing surface became the mounting diameter for the ABS ring/wheel so maybe/just maybe they could be either used or be able to be machined to be used. I've never seen the ring/wheel offered by any of the after-market sources that offer them. There either may have been or maybe still is but I've never needed or seen them.

The rings are pressed on.

Yah looks like their is 3 types 84-85, 86-87, 88-96. Don't really see any seals, just the large washer. Wonder how hard the ring comes off an 86? Maybe a semi cut and a good smack with a hammer n chisel.

'84s and '85s don't have ABS, so those spindles wouldn't work unless you are willing to give up the ABS (I wouldn't).

What is your interest in removing the ABS ring. Your car is an '86 and the ring likely provides a "required dimension" for assembly. I can assure you that an '84 and '85 have an inner seal. ABS rings or tone wheels have been sold in the after-market for years as a service part but I've never seen one offered for "wheel-speed" from GM. It's always been part of a greater assembly.

The knuckles are also '84 - '85 and '86 - '87.

Car will be used for drag race. I'll be removing the abs and the ring is just another part I don't need and rotating mass. I know small diff, but death by a 1000 cuts!

Please don't turn my thread into a debate!
