I've been disassembling my 70 Dart Swinger. I removed the heater, and shoved my hand up and over the heater plenum. What a bunch of junk I found, ( tree needles, leave reminants, and general yuk.) I plan on removing as much as I can manually, and then snaking a vacumn hose up in there to get as much as I can. May use the compressor as well. I don't know what I will do with the drivers side yet. Just thought I would pass this along to anyone whos doing their car, and has not checked this area. There is no place for this stuff to go, except into the lower cowl drains. I know this has been discussed in earlier forms, but it's a good thing to be aware of.
