Aftermarket Heat/Ac

[6togo]

Anyone ever done a aftermarket Heat-A/C conversion on a G body with good results or even just heat to clean up the firewall?

I've not done it since my car has AC stock, but I'm interested in upgrading. It looks like Vintage Air is trying to put something out for our Gbodies. I check this thread every once in awhile to see if there are any updates: http://www.turbobuick.com/forums/thread ... ne.391683/

Probably a few more hits on this site if you search.
