Default BW T-10 transmission size?

I'm going to rebuild the 4 speed in my 78'. Got the overhaul manual out, and it lists 3 different 4 speeds: 76MM, 83MM and 117MM. How do I tell what I have?

I'm not entirely sure what that is referring to. Do they specify what is supposed to be 76mm, etc?

Unless it is something to do with ratios? Does it show 3 different trans?

Since 76MM is 3" so I'm thinking it could maybe the diameter of the flange that mates up to the bell housing. The pictures of the 76 and 83 MM look simular, but the 117MM trans must be a truck since the shift lever comes out the top of the trans. (I don't have the trans out yet to measure anything)
