Does anyone know Denver emmisions standards for a 91?

Double posted here and CFSJA.

I'm trying to get my new 91 ready for title transfer and I've run into a snag. There is no way it's going to pass emmisions the way it is now. Almost every emmisions control system has been removed.

But I can't figure out just how tough the test is going to be. How much hydrocarbon it's allowed, how much CO, NOx, etc... Does anyone know how tight the standards are? I'd love to see a test sheet from a 91 that passed.

I'm hoping it will pass with just a few CTO's missing. I've been able to track down most everything else. I plan to hook it just slightly simplified. And with a non stock air cleaner. The EGR, AIR, PCV, Charcoal cannister, and etc would all still be present and functional.

The big pain in the rear is that I'll have to make it pass within a month of my buddy signing it over. Jeffco will issue me a temporary tag to be able to take it down for testing. But if it doesn't pass within a month of the date on the tag I'll have to have it towed to the test station for any further testing!

I almost wonder if I need to go with the 50 state legal Howell kit and not mess around with the stock system. I might find myself employed in California in the future. Is California's test going to be even harder to pass than Denver's?

Wagoneers are considered trucks right? No third brake light so I assume so...

Well yeah, but what does the EPA classify them as. Now I'm going to have to do a search.

It's classified by the EPA as a Special Purpose Vehicle. So technically it's a light duty pickup and adhears to emmisions standards as such.

Necro Bump for Denver FSJ’rs.

Recommend Econo Emissions on East Colfax in Denver. Shop is not much to look at but IIRC shop owner’s name is Moses and he is on it. DMV lists them as indy emissions test site for older vehicles.

I was puckered up worried that my 78 would not pass go as all the emissions equipment is stripped including no cats on the exhaust. Passed rather handily.

YMMV, good luc.
