Not sure what you mean by duplicating the kit parts? I actually don't have a DB-01 kit. The intention is to build a chassis from option and replacement parts alone, hence the list of doom...

I'm still missing the bearings, turnbuckles, and a few other knick knacks.
As for the B44, great car, but I'm just not a fan of carbon fiber double deck offroad cars. I've always been a Tamiya/TRF fan, so this seemed the natural route to take towards a tub-chassis 501x. Til then the trusty XX4 will have to do! I've also had my eye on a Kyosho ZX-5 SP, but they're out of stock until the end of September over here...
