Converting Metal stegadon to engine of the gods

[WadeTheMediocre]

I received an old metal stegadon today, and I'd like to be able to field it as an engine of the gods if I wish. From pictures(having never seen one in real life) the difference I can see is trim around the basket, which shouldn't matter too much, a skink priest rider, which I can supply, and that big ring in back, which I think is probably necessary. Anything else I'm missing? Any suggestions to make my quest easier?

Hi, I have got a Stegadon with engine of the Gods...
The difference between the two Stegadon is the circular ring... Inside the ring there is throne...
There are five skinks... Two bring standards, two have javelins and there is a Skink Priest or Hero...
There aren't any other difference...
In my opinion the throne isn't necessary... It's enough the ring and a skink priest inside it... I would put the standards only for a aestethic point of view...

Have a look at bit suppliers you may be able to purchase just the engine parts.
