Do you still need help finding those part numbers? Let us know and we'll chime in.
The bearings are a bit involved but nothing difficult. best to do the driveshaft and bearings all at once. I believe the TT01 bearing kits include the prop shaft bearings so you might as well do everything together. I'm not sure, but it might also have bearings for the steering.
Yes, this means some disassembly but it's no different than building the kit in the first place. Much less involved though because you'll be taking it apart in major sections rather than down to the last nut and bolt. We've all been through it !!
Just so you know, Many racers tear their cars down after every race day just to clean the bearings and check other stuff. Then again..some of us are old and lazy + we're not good enough to worry about the 10ths of a second it might gain us.
NICE JOB ON THE BENZ !!! BTW, you make take some jabs for those long body posts but my suggestion is leave them long. No use starting a body post collection yet. You'll probably go through bodies much faster than body posts.
