[WANTED] 8 1/4" Sure Grip unit...if it exists

[71SlantSixDemon]

Hello all. I am looking for a Sure Grip unit for my 8.25" rear end I'm installing in my 73 Dart. I'm told these exist but not sure. Let me know any information anyone has on this type of setup. Thanks for reading.

In addition, Jeep XJs and Dodge Dakotas up to approx. '96 model year sometimes used the Chrysler 8.25 (after ~'96 they went to a 29 spline axle- you need the pre- '96 27 spline unit) and they commonly had sure grips and gears in the mid to high 3s. Time to hit the boneyards.
Dana 30s (IIRC- or is it 35s?) also used the same limited slip unit.

This is what I plan to run: Dana Spicer 75101X: Diff Case Assy Kit - JEGS High Performance I tried to look for a used one but all the junkyards had were 29 spline and no luck with a wanted ad on here. $20 off now with Jegs or $50 off if you spend $500.

Also if you have 2.45 gears and numerically lower in there now in the case you have to stay in that range, say 3.55 will not work in it. just FYI

Dr. Diff sells both sure-grips and ring/pinion sets for the 8.25.

Only 29 spline though.

I stand corrected, I apologize @halfafish I was just on there last month looking and 27 spline wasn’t even an option.

No worries. Life is a moving target sometimes.
