We also don’t have the other BS laws, yet. Still a bit of old iron on the road hereYup scratching Colorado off my retirement list.
Every year????even Kommiefornia is every other after 75 ant not until 6 years old on new models.
There is a bill to move the cut off to 80 iirc. Fingers crossed.
Fyi my 77 is registered in Mohave county, no smog test. 5yr tags 126 bucks 1 yr in CA is 200

Luckily I live 4 miles outside the testing zone in north Weld County.My county is emissions exempt thankfullyI only went with collector tags for the cheap registration.
There's so much different information about it, I can't find the information I found last time I looked. This is the closest I could come:
B, COLLECTORPLATES
1. They may be obtained for an automobile, truck or truck-tractor manufactured in 1975 or earlier.
The plates are issued to cover a period of five years trom date of registration.
2. Taxes and fees paid to obtain the plates are five times the annualtaxes and fees
that would be imposed tor a single year, except that the amount oi the road and
bridge fee is impmed for one year only of the five - year registration period.
3. lf the vehicle is registered in one of the counties that require vehicle emission testing, it need be
tested one time only, prior to obtaining the plate. Renewalof the registration at the end of each
five-year period thereafter does not require re-testing for emissions. Emission equipment
originally installed on the vehicle at the time of manufacture must be retained on the vehicle.
4. li the vehicle is sold or transferred, and is to be re-registered in a county requiring emission
testing, it must be rctested.
5. Prior to September 1, 2009, applicants were able to obtain collector plates for years 1976 and
later, so long as the vehicle was 25 yean old or older. Thus, some vehicles currently bmr
cotlector plates even though the vehicle was manufactured after 1975. lf such vehicles are
sold or transfened, they no longer are eligible for collector plates.
6. The plates are placed on the front and rear of the vehicle, and applicants may obtain them as
personalized plates, such as "ILUVETS", if deshed.

This is what Boulder County says:
2020 Emissions Exemptions
The following vehicles are exempt from emissions requirements:
The following vehicles are exempt from emissions requirements:
- Gas/Hybrid/Alt. Fuel vehicles are exempt for the first seven model years. (In 2020, this means vehicles that are 2014 or newer are exempt).
- Exception: If vehicle ownership is being transferred in the last year of the seven-year exemption, an emissions test will be required. (In 2020, this means that a 2014 vehicle will require an emissions test if there is a transfer of ownership.)
- Gas/Hybrid/Alt. Fuel vehicles are exempt for the first seven model years. (In 2020, this means vehicles that are 2014 or newer are exempt).
- Vehicles 1975 and older with collector plates
- Vehicles 1976 or newer that have been grandfathered (i.e. registered as a “collector’s item” prior to September 1, 2009 and registration has never lapsed/expired/or had a change of ownership)
- The following vehicle types are exempt: kit cars, all-electric vehicles, motorcycles, horseless carriages, and vehicles registered as street rods
Congrats on getting it on the road again! 
@Bowtiek10 dude! I live down the street from DU, not more than 5-10 minutes. I would love it if you stopped by!
@max 02 thank you so much!
@Wes Harden unfortunately I need to get it emissions tested every two years. Better than yearly I guess. My understanding of the law here in Denver is that it has to have all of the emissions-related stuff that came on it from the factory. So unfortunately for me that means cats, O2 sensors, and AIR pump... not sure whether it came with an EGR. If it did, I need one of those as well. They test for HC, CO, and NOx on a "treadmill". The test is called I/M 240 Dynamometer 'Treadmill' Test.
I truly do not mind spending some money on the exhaust stuff for this truck because I knew from the get-go that I would have to. I have done some basic reading and it looks like I would need a "manifold-back" exhaust system because I do not know how to weld. Due to that my goal is to find something bolt-on.

Gimme some time and I’ll run up a parts list. Have a budget?
Honestly, if I can do it for around $1500 or less that's my main goal. First priority is passing Denver emissions, second priority is minimizing power loss, third priority is cost effectiveness.
My Dad has collector plates on his '85 El Camino. He got them before 2009 so he just renews them.
Look on the radiator support for an emissions lable. It will show what it had from the factory.
Take a pic of the spid lable in the glovebox too. That should list which emissions option it had when ordered. That will help determine original equipment.
I'm really sure you never had O2 sensors on that truck.

x2 the sticker on the rad support . this is the federal sticker that all states that do testing go by .
Yeah I don't think an 86 K30 had cats? what is the gvwr? over 8500?
Ok, I dug around in the GM Heritage Center website to pull up the dealer order guide for the '86 trucks. Here's some pages from it with the emissions requirements for the K30 trucks with Federal Emissions. Items to note, no cats over 8,600 pounds GVW.
Here is the descriptions from the guide for what the equipment is:
From a visual standpoint, the kids at the emissions testing center are going to look for the obvious items. EGR, AIR-injection, PCV, Charcol canister for the evap system, and factory air cleaner with hot air stove on the passenger side exhaust manifold.
Now the question is to inventory what's missing from this list.

Yeah man some time during the week because I leave Denver on the weekends to retreat to the mountains, the city is a little overwhelming
Back in my early days at GM/Chevy, I worked right next to the group that assembled the restoration packs you could order through Chevrolet Customer Assistance at the time. Needless to say, there were many lunch breaks with my nose looking through the old books. I'm a nerd for that kind of stuff.
@shima take some shots of the engine and under the hood to allow us to scope out what the truck has or doesn't have. That should help you get a shopping list together.
When I was at his place I'm pretty sure it had an aluminum intake, aftermarket carb and pretty much no emission stuff. Seems like something was going on with the exhaust manifolds as well but I do not remember what it was.
Good point, Drew when you post up pics remove the air cleaner and get some shots of both sides of the engine.
