If you are going to spend the extra $$$, then Ashcroft's HDP38 complete centre ( with air locker ) is your best option.
Easy fit up as it bolts straight in, strong as a Salisbury if not stronger, maintain your ground clearance, it's brand new of the shelf (won't have hundred's of thousand km's on it) and dollars will be within the ball park for Salisbury replacement.
Just my thoughts......
