Tantalus dimensions?

I'm thinking about creating a Tantalus out of an old-style Ravager and Raider, the better to match 99% of my Dark Eldar forces. Before putting knife to plastic however, I was wondering if someone could give me the approx. length, width, and height of the Forgeworld version.

Please?

Length: 10 1/2 inches
Width: 6 5/8 inches
Height: approx: 8 1/2 inches not including base/stand but including rediculously huge sail

Height without sail is just over 5 inches, and thats the rudder on the back of the tantalus

Thanks much!

It's an old post but I'll try my luck:

Is the above mentioned width at its brightest points? (scythes) or just the regular Hull?

I am trying to compare it to an Akhelian Leviadon to convert it out of one
