building 8 3/4 489 section

do you really think the centersection of a 8 3/4 is so weak? I am having this C/S in the car since 2001 ( bought the car )guess it is in since the car has been built in 1972. was from 72 to 2015 a 3,23 R&P and 4.10 just the last year. No wear, no damages. All what broke is the clutch ( worn out quicky ) and the rear U Joint this July. ( 7290 ).

J Par, i don't think it is the power thru the Manual gear box that made the caps break. Maybe overtorqued, invisible cracks inside thru the years? Scary anyway...

I don't wanna go the DANA way. Super expensive and I can't Change the ratios between the races for Long Autobahn Cruises... :)

Do you think a swap to 4.56 is significant or should i step to the next shorter? Ring and pinion manufacturer are not the same in Quality. Who is the best in your eyes?

will try the calculator from above.
