Maybe not that bad, but after all these years of use or abuse, they could it be some damaged, so not a guarantee of good working conditions.
Being the clutch kind are easier and cheaper rebuildable, kist are everywhere, and able to make it at home, thats an advantage. Cone kind will need to me machined as stated, not too cheap to make that.

Not sure what it cost to rebuild the clutch style but gringing off a couple gears and adding washers can't be that expensive.

I like to burn rubber. Alot. As in 100 ft or more through several gears. Out of all of the Sure-Grips I have had, only one was a cone style and it seemed to "fishtail". Maybe it was worn out. I swapped it for a clutch style with the same ratio and now it burns rubber straight as an arrow. That's all I know.

Yes, on the street where there is good traction, (versus the test n' tune track, where they really don't give a flying flip whether you get good traction, and the kidz dump their A/C fluids) , my "sure grip " fishtails , too. Good luck finding a clutch unit, though. Limited availibility, no ?

Actually, I would have gone to a clutch type ( for the rebuildability thing ), but they are not available for the 9 1/4 diff. Per Auburn gear, the check to see if your cone unit is still serviceable is easy ( applies to a 9 1/4 - don't know about others): Jack one tire off the ground. Put a torque wrench on a lug nut on that wheel ( radially out from the wheel center ). Break-away torque for a new unit should be 70 lbs or better. They claim the unit is serviceable down to 20 lbs. Below that, replace. They also suggest 80-90 gear oil only. No synthetic. An additive os ok if you have bad chatter on turns.

I have had VERY good luck with them. The 741 2.76 SG I have in my 62 Belvedere right now came out of a 74 Monaco with 170k miles on it. It has been in there since the middle '90's, has run as quick as 12.30 and as fast as 5200 in high gear ! It is as tight as a drum !! ..

they ar ok..just not good on longevity as the cone wears it eats into the case and puts metal shving in the oil most I have seen used have not had very good service on the oil change and the bearing are pitted up but when in good working order they are just as good as a clutch one IMO just wont last as long with out preventive maintanace and oil changes look it over good so it not 700$ after the 300+ $ used I have had one redone,its tight as a ..... well it chatters the tire on turns so its a grabin good lets say runwhatyabrung

Clutch types are available forthe 9.25 all the suregrip truck axles are a clutch type LSD. I know because I took one apart, and sold the empty diff with side gears to a kid who was going to rebuild it and put it in his Dakota--I pulled it out because it needed rebuilt and i wanted to go with a detroit true trac
now, if you're talking about an old 9.25 from a car, I don't know if they make one for that specific application (did the spline count change on them?) if so, you could buy one meant for a truck axle, and just get new axles for your older diff

Good info - thanks. I didn't know that. The 9 1/4 I have came with the car ( 79 300 - Cordoba ). It was originally open and I added the Auburn center section - cone clutch. I'm not having any problems with it so far. I'll probably stick with it for now.
