Novak Replacement Option for (original) HV ESC (P/N 3220)

i have a hvmaxx 4.5 system (broken) that i want to upgrade to the hvmaxx pro w/ 6.5 and a 5mm shaft, however i am having a hard time filling out the paperwork....

i need to do this in the next couple of weeks


can you tell me how i need to fill out the paper work and also do i need to pay the extra $15 per component because they are the new version?

so what is the total cost for a trade up to the newer esc. and also change the motor for a diff. turn


thanks so much
