George:

You need a ~complete~ lower hull, basically, right? What the buggy & truck guys would call a " roller ". To be honest, the cheapest idea would be buying the static Leo 1A4, and a pair of gearboxes, then selling off all of the upper parts.

For good prices (FORGET Borgfeldt Toys!) you should ask Karen @ [email protected], or with Dave4What via his eBay store or his website [link=http://www.rareplastic.com]RarePlastic.com[/link] Lowest eBay price for a Leo 1A4 kit I see is $333 & $61 shipping out of HK, cheapest US is 500+ & shipping.

That said, did you want the NEW DMD gearboxes, or the old 540 clutched units? If you want the clutchers, let me know... be easier for me to upgrade mine with the new hull pre-punched for DMD's. I might even be able to help with unloading the hull/turret parts.

PS: The one Dave has up on eBay, the 4601... its got a PLASTIC hull, suspension arms, and tracks. Completely unsuitable for a decent RC chassis.
