I know you can't rebuild them in the conventional sense. But how does their strength and actual traction capability compare to a clutch-type suregrip?

There is a 489 case, 3.91, cone-type suregrip available locally for $300. If I gamble and it works, it could save me $700 or so over getting a rehabbed center section.



In my opinion the gear-case-yoke is worth close to the asking price. The sure grip is a bonus. Sure its not the better of the 2 but it may hold up along time. I did break the cross pin in one about 7 years ago. 3.55 gear, 28" slicks, 3600# car and 12.50's 1/4 Probably had a couple hundred runs on it b4 it broke
