You might be able to make it with just the shift shaft. Which wouldn't require a tear down. The value of what i post is what you pay for it. I don't always do things correctly and this was a long time ago before knowledge was easily shared. If you are in a hurry and trying to do this in a couple hours mind the circle clips and keep the flat side out. Don't ask but same goes for replacing lock tabs.
If you are going to buy a manual i'd get the factory or a pdf of it.
Be sure to get to the parts girls bottom end though ,sounds like a score. Good luck
