What I should replace

Conversion kit from plastic to alloy diff
A alloy big 2e gear carrier
A hard steel first gear
And this you have to do when you tune it because I already broke them
Wheel squares hardened steel
And at last make a good cover for your air filter
Some panty or so

I hope you all understand what I just told you.
If you have any more qeustions just let me know ;)
