What does it need to work?

hey guys,

ive come across what seems to me to be a good deal for an 833...its for an abody (ive attached a pic of the casting number since im not sure what year its from and what the ratios would be)...The owner is a great very straight up guy and he says it needs a new reverse gear (Which he sent me a pic of because its all worn out and grinds going into gear...looked for replacement gear on brewers site but couldnt find one so not sure what they cost) and a reverse shift rod (think i can get one used for cheap but not sure)

im not a tranny expert so i thought id ask you guys if there is anything else missing here that me and him dont know about...also, i believe there are 3 shift forks, but he only has 2 and then a spare (so im assuming reverse is missing, or maybe im wrong and reverse is in the pics as well)..anyways, i'll post the pics and whatever you guys think it needs please let me know

once again thanks all for helping me with my neverending questions in this section8)
