Dogs of War

I have an old charriot of Chaos force.
I'd like use it for my paymaster as Midas does.
I'm looking in the 6th-7th edition errata for Dogs of War but i found no cost for the Charriot, and i have no rulebook now.
Someone can tell me how much points it cost?

Thanks

You need the rules for Mydas to use it, a normal paymaster cannot take a paycart (as the chariot is called).

So simply have i to use Mydas rule and change name and mini?

Well, you could use the model and name of Mydas if you wish, but for all gaming purposes, you have to use his rules, yes.
