...or maybe design something like this for Fibre-lyte?

There is a proper tt02 cover shell from tamico

Tamiya 51359 Nissan Xanavi Nismo GT-R r35 45€ + shipping (worldwide)

I have some spares High Torque servo saver, but I have not the Q4 part. I can use only a washer/spacer to lock the servo horn?

Full code is #19804237 (for Levant, TT02 etc)

Which gearbox joint? #54477 #04237

Take a look at Tamiya #54587 (wr02 servo mount) from manual it seem just a little bit longer...

I do not think you can find a servo mount for lunchbox, but probably some hopup (for tt01 or wr02) can be a direct fit. Servo saver Tamiya #51000 is a good option.

Yep, but I did not get usefull result. Yes, but with paper all seems good, maybe the paper test is not so much precise to spot this issue. Yes, the motor has 6 holes, I will try.

On youtube The 8-Bit Guy deal with this stuff for his restoration. Take a look.

My goal is to follow the same path of tb01 and build a modern off road truck. Spare parts for tb01 are out of stock or hard to find, so I'm investigate alternative ways (in addition to tt02b).

I have standard Thanks for the setup. I have TRF big bore shocks, so I will try the #54221 spring set. The setup suggest 2 holes, I have pistons with 3 holes, but I thinks the size are different, bigger for rally car, I'm right?

You are right... I did not remember well.

My first RC was a DT03 after some years of mini4wd, But my first rc ever is this beauty:
