I've pulled the old Suburban heater out of my 71 Ambassador. I'm going to heat with a Wave 8 instead. When you pull the heater it leaves a housing which doubles as the beginning of the plenum. I want to get that out and recover a large storage area, but it will not come out. I cannot see any rivets or bolts holding it. It will wiggle maybe 1/8 to 1/4 inch but will not budge further.
Please tell me that it is not attached to the AS through a welded bolt on the bottom of the housing!
There is a lot of info on getting the heater itself out. I found good info and did not have much trouble with that. Now I cannot get the housing out.
