@rio1856 here's an album of pics when I rebuilt this transmission a couple years ago. It came out of my 71 Cougar XR7 back in 2006. I abused it quite a bit, and whomever had it before me did too. If you go down to the pics of the sliders, you can see where material had been displaced on the splines. I replaced those and checked everything for straightness. A friend had twisted the input on his toploader a couple years before, so I was conscious about looking for that, but this *was* good at the time.
@Stanglover the roundabout works well, most of the time. It's only the ones that stop to let people in, and those that don't understand what a "Yield" sign means that muck it all up. The DOT completely rebuilt this one about ten years ago to make it tighter and help slow people down.
