so i got everything out and done. only thing left is, what to do with the holes on the firewall. 1's HUGE!! and 2 small. Do they sell plugs? I would love to cut and weld a new piece but didn't want to do that now. Any ideas?

 

go to home depot/lowes and in the screw drawers they have rubber plugs.. may also find some in the plumbing section.

 

Question, why would you remove the heater and not reinstall? Defroster is important!

 

not to me. imo defrosters are useless on 65/66. plus i dont need all that crap under my dash. looks way cleaner now

 

must live in Florida.

Dont trash the box and components you might be surprised of the price they will fetch on fleabay.

 

Make a cover plate that bolts on it would be best in case you change your mind later.
