easier still graft a coil rear end on it.
the way I see it you have a great opportunity to buy a 4.2td coil cab ute for $28000 and you're not going to take it.
I and many here would be all over that like a cheap suit. Straight up you save $4K, If you don't need load carrying capabilities
Throw some parabolic springs in the rear, you may be very surprised. M2CW
