i replaced a 4AFC with a 100kw 4AGE. not a hard thing to do from the wiring side of things.
i think there may still be a writeup on toymods about it
i'll help if i can :)
Spotted: KE-1968 - Kermit Green KE10 at the local swimming place here
Credit to owner - great looking little car - even my Mrs was impressed (she used to have a Mustard KE30)
theres a good silver called GM steel wheels. its a good reflective silver, i used it on the frame of my TA22 lights.
well done this is an awesome thread and a good deal of commitment to a build. good work indeed.
