So, after receiving my rebuild kit for my 343, I've gotten a little stumped. Seems a I have a few extra parts that don't necessarily have a place they seem to go. I will add some photos. Other questions: do I need to use any assembly lube for this? I was thinking of using the Valvoline Synchromesh gear oil for assembly lube and also to fill the case. Should this Synchromesh gear oil work good? I heard these transmissions were sensitive to oil weights. The first photos of the O-rings, I cannot seem to find a home for them. The kit is a Saginaw 3 and 4 speed kit, possibly extra parts that the 3 speed doesn't use? The last photos, of the side cover and shifter forks, are then O-rings in the proper location? I can't seem to find a location to put the o-ring on the shifter arm/fork that has a notch in it, so I put it all the way down at the bottom of it. Also, the side cover has a part in one of the holes that seems to hold an o-ring, is that where the o ring goes? If so, how do I get it in? This is also shown in the photos.
