There is option c babs that will require a bit more planning but could get you what you want?:D
Buy an old td5 ( best of them are pre 2003 with the Salisbury that can be strengthened to Dana 60 spec)with abs/tc and a stuffed engine, then do the ls3 plus auto and fit out the dash as you want, maybe toss the factory ac and go a red dot ac unit (like another bloke on here did from Qld )on the roof with vents from a middle head unit on roof inside wagon. While the engines and transmissions getting swapped get them to install an acre of dynamat if you don't want to hear the v8 to much :twisted:. Then sell your puma defender to just about cover the cost.:D
