The new 104v2 looks to have the rear pod of the RM01 1/12th chassis.
The too bad they don't scale up the RM01 into the F104 size.
The hex's & front axels look close... what is the dia. of the rm01 & the rubber F1 tires?
Here are the non-race kits with ABS tub chassis & bushings.

I think Lambert has the mounts & has put the Nissan body on his F103? chassis.
