So your box is out 1/16”
And your firewall the same 1/16” it would seem.

If you cant pound an outward bow into the firewall then you might take the time to make a thick iron bar stock reinforcement bar to span that gap area when the box is bolted on .

A 2” long length of 1/8” thick bar stock would be quite stiff.

Kinda the same idea as a valve cover load spreader bar.

It would not look stock if that might matter to you, but it might get you 1/16” closer to having no gap on top.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
