Sprocket cost ???
Special tools - regular tools and two large adjustable wrenches for the large wheel nuts - lock tight - bailing wire to hold up brake drum assembly while wheel is off or watch the brake line break - a lift is necessary - up and down a number of times -
Difficult? Tedious, very dirty as when you have to change it out, the aluminum has been reduced to aluminum oxide powder (black dust) and covers everything! Once everything has been changed out then the tedium sets in to get everything aligned just so. Final test is on the lift with wheel suspended and fire up the engine in neutral then gently putting the shifter in fifth gear but not all the way. Let the synchro do the work and get that wheel spinning so as to see where it tracks. Once that is done then put everything else back together
