Not sure if it was offered in any year (possibly other models)  but the way your describing the action of yours it looks like an open carrier (non- Sure Grip)

Yes, I have seen light duty "741" units with 2.76 Sure Grips.
" I have spent thousands of dollars and countless hours researching what works and what doesn't and I'm willing to share"

its a 489   the numbers read 2831489.
If it was a sure grip wouldnt both tires spin  same way on jack stands? has a 276 tag but no sure grip tag.

yes, and if it spins the other way like yours does, its an open diff (non-suregrip)

Sure-Grip was available in the 8 3/4" with all ratios in all years from '58-'74.
Pardon me but my karma just ran over your dogma.

that's just what a single wheeler does, if was sure grip or track lock both spin the same direction but sure grip under torque
