WANTED heater delete

[cuda hunter]

I'm trying to find a heater delete set up for an E body. The B body was the exact same set up with a few minor difference's.
I'm curious if anyone here can identify any of the C body's heater delete set ups as being the same as the e and b body heat delete.
I've attached pictures of the delete box, and the mount to the dash frame. Perhaps someone can advise me as to these being similar to C bodies.

This part would be the hardest part to find.

And I forgot this picture. This is the block off plate for the firewall on the E body.
Different from the firewall block off on the B body in the third picture first post.
