OK, got the info from its current owner. It started life as a 6 cylinder WB. In 1988 it went to Brock and was converted to 5.6 litre, had the stato interior and suspension Brocked all for around $20000. So big dollars in 88! It appears it is the ute I knew round here.
The other point is that it is the ONLY Magnum ute built.
So its white, 5.6, stato bench seat, column auto, stato dash. It started life in Tamworth NSW and hung around the area for years.
