A-Body 8 3/4 open gear 741 case

man am i out of touch with prices,,450 for a rear needing rebuilt?? OUCH,,,and i wouldnt be concerned about the so called week 741 case,,,the 741 case still has a bigger pinion then the all mighty ford 9 inch,, a friend of mine ran a 741 case in a 340 4 speed dart with slicks 456 gears and beat the crap out of it,,,never had and issues with it,,,
