I had forgot to mention that I changed the entire rear clip about 1' from the back...

This car was rearend-ed sometime early in its life and it destroyed the tail-panel...

Separated it along the seam in the trunk floor and down the sides...

With the new trunklid on everything fits pretty good now...

Before the change nothing was even close...

I also swapped out the 65 B Body 8 3/4" for one from a 63 B Body to narrower the rear an inch...

If you zoom in on the images below you can see the difference...
