Don't listen to these guys....The weakest part of an 8.75 rear is the stupid adjusters which is a bolt in the center of the cap.
The billet caps from MW will make your 8.75 a much better piece and it's more the Enough strength for 90% of the mopars out there.
Me think you mean the stupid boss for the retainer bolt for the adjuster, yes? The left(driver side) cap usually breaks at that boss first which destroy a bunch of other parts, been there, done that
The last 8 3/4 I built and raced ended up bending the housing bad enough on the passenger side to rip the ladder bar mounts off it during a run at the starting line, NOT GOOD
OP, if you do decide, or anyone else who wants to drag race a 8 3/4, do what ThumperDart did, add a backbrace before starting to race it
