The only thing I could find was a top view of the Bronco:

I believe the MoD bought the Bronco, but with some serious mods before delivery as the 'Warthog'. For example the Warthog has a front centre turret, but the Bronco has two roof-top hatches at the front, one on the left one on the right.
Hope this helps.

ps. I hear the first Warthogs were delivered in September. No doubt they will try to rush them to A-stan after trials.
