Removal of A/C-heater box?

I just did this to mine last week. The link that 67Dart273 has put up on Heater Delete VENT? has alot of good info. Just keep in mind if you want to replace the heater with a heater from a non A/C car the firewalls are different and will not be a direct bolt on. Therefore, I am keeping all my parts. Just FYI before you sell or through anything out. It sure makes for a lot of leg room!!
