I'm about to undergo this myself this spring after a 2 year rebuild
(engine/body/interior). I did some digging around the Illinois EPA site
(http://www.epa.state.il.us/air/vim/enhanced-testing.html) and came up with the
Emission testing is only performed on '68 and newer vehicles with the enhanced
dyno testing done on '81 or newer. Your '72 (and my '70) will still be tested
using the old idle test.
It appears that the regulations follow the registered model year, not engine
A waiver will be issued upon failure of subsequent testing if, all original
emissions equip. is present and operating, and a maximum of $450 is spent on
repairs by a recognized repair tech. in order to get the vehicle to pass.
Positive improvements must be shown in the 2nd testing.
SO, it appears that you (and I) may luck out, it we can hobble in and pass the
first time, without inspection and $$$ outlay. My suggestion, find a repair
facility with a calibrated gas-analyzer that will work with you to set your car
up to pass the first time and keep your fingers crossed.
