What does it need to work?

Wow, and here i was thinking that yet again this was gonna be a good score...either im naive or dont know what im looking at or both, so once again thanks guys for leting me know about the problems

I figured that there was a 3rd fork for reverse from looking at other pictures of inside of cases, but i guess im wrong
Also, i kinda figured you couldnt buy a reverse gear by itself and if i have to buy a whole new cluster gear then forget it
I also noticed that needle bearing (i thought it was a pin of some sort) lying in the bottom of the case, but i wouldnt really know how good this thing was until i went to go look at it and im asking you guys to see if im wasting my time going to look at it
also out of curiosity, what are those shifter rods for then? (I knew they didnt look right, but he said they were for it)

thanks for all the input guys...the trans he was offerring to me at 100 bucks, which i thought was a good deal until hearing all this
