727 tailshaft housing

Don't forget there were 4 different output shafts used on 727's. Make sure you get the right one for your year trans. Here's a picture of the different shafts. There are small identifying features towards the back end. The front spline angle is also slightly different but it's such a small amount you can't tell it by looking at it.
