Thanks Shayne, I realise this was going a bit off-topic!
Anyhoo back to the matter in hand.

The Jag IFS is a stout unit...these Jags were heavy old beasts!

The back ends can also be 'prettied up' really well too.The inboard brakes keeps the unsprung weight down and the hub carriers polish real nice.
There is a good line of aftermarket diff covers available. (at least over here there is)
Plus they're as tough as old boots!
They're a favourite of 'us Brits'!

They reckoned pound for pound (dollar for dollar) wink The Jag rode as smoothly as a Rolls Royce of the same era.
It should make your truck ride and handle nicely.
Good luck
