Those Jag rears are not the strongest for drag racing, they are however great for the occasional drag strip day,and spirited track and road use.
Some had Salisbury and some had Dana internals, the easiest way to spot the difference is the front driveshaft input flange which is round on the Salisbury and rectangular on the Dana. Salisbury has clutch plates and the Dana a cone clutch.. I prefer the Salisbury but others prefer the Dana..??
