Gear Vendors or swap for performance 5 spd OD?

I have an E-body so not sure how different the A is going to be but can’t imagine it’s that different in the area I had to work on. I only had to make two small dimples in the hump one where the speedometer setup attaches to the unit and one where the top of the unit met the tunnel. I have a TTI exhaust so they make a special H pipe for the GVOD setup as you will have to move the “H”.
