I think I will hold off until I hear from others who have tried installing the super case in there 67-69 bird. I would like to see if there are any fitment issues that have to be corrected. Also any issues with the Hurst shifter.

I think I may learn how to rebuild these gearboxs and order the m22z gearset and put it in mine. That would be a nice little project over winter. If I don't like it, I just swap it back out.
