How important are these pipes to passing emissions? I could rig them up to appear to be connected..
I have the manifolds and some smog crap from the ‘88. If you need/want you can have it.
Can you check the size of the threaded holes for the air tubes?
I have a couple plugs left over. I’ll see if I can figure out the size.
You are correct. My manifolds have 1/4" pipe thread holes and my tubes are some massive metric size.
I'm not sure exactly what size the metric fittings were,maybe 16mm--I seen to recall a P/S hose fitting off a 80's GM vehicle had a 16mm thread (not sure of the pitch) I had hanging around that I used to plug one of the tube holes in the manifold on one of my trucks when one tube rusted away..
(I just screwed the fitting in,cut the P/S tubing off with bolt cutters and brazed to seal it to the fitting,I didn't have to pass emissions and just wanted the exhaust leak plugged.)..
A thread pitch gauge would tell what size & thread pitch the fittings are--maybe adapters are available or could be made up out of NPT bushings so you could screw the existing tubes into the manifolds..beats having to buy new tube nuts and cutting off & re-flaring the old tubes,they may not survive that..

Thanks Chris, but I think your '88 manifolds are smog equipment are different than my '84.
I got my tubes and air pump from a 1985 Suburban, which were identical to the 1986 Blazer nearby. One large air tube port per manifold near the front cylinders. I assumed they were the same as what my 84 had originally.
However yesterday I saw this 1984 K25 and it had 4 smallish air tube ports per manifold. Not knowing what manifolds I have, I left them in the yard.
I get home and realize my manifolds have the same multiple ports.

Crappy pic but I have the manifolds and tunes of off a 84 suburban I had you can have them but shipping may kill it’s could bring them to blazer bash and maybe someone else going may be closer to you so you could arrange a pickup.
Holy cow, that would be awesome. I'll check to see if any Denver area guys can bring them back from Blazer Bash.
So I've got most all the smog stuff installed and connected, except the fat hoses from the air pump to the exhaust manifolds.
Installed a universal cat and a turbo muffler since my muff was dented and leaking. It's quieter now than it was before, which is a little disappointing. But since it's a basic 350 with a wimpy cam, I guess I'm not missing much on the Cool Sounding Exhaust metrics.
Les Schwab wants $35 per wheel to sandblast and powdercoat most any color (including Argent Silver!), which is cheaper than some sandblasting shops quoted me just for blasting and no paint. Remounting and balancing works out to $15 per tire. $175 for 5 essentially brand new rally wheels seems fair to me.
Here's a picture I took on the way to work today and one with a Steiger earlier this week.

How hard is it to remove the top by myself? The kids want ice cream.
Not impossible, but not fun. It's heavy and cumbersome.
I did it a while ago with a friend. Two of us were able to get it done but it was painful. Would suggest three people or picking it up off the back of your rig with some sort of rope/pulley system.
As an aside I am going through the exact same emissions struggle in the exact same city. Just a different motor. I might reach out to you with a few questions if you don't mind once I get around to sourcing and installing all that emissions stuff.

Hell yeah. I have no idea what I'm doing much of the time; I'm just having fun trying to figure it out.
I suppose that's a fitting allegory for life, if you think about it.
The photos I take at the junkyards really help, but I've learned that there are sometimes minor differences between model years and even factory options that affect what parts will work for your application.
I think all I have to do is pass a sniff test and as long as it visually appears to be functional, I will be in the clear. We should know on Monday when I take it to get tested.
Agreed - if all the parts are there, they will probably fill in the checkboxes. They won't check to ensure it is functional. At least I hope they won't, because that would screw me too.
I should probably slow down when I hit up the yard.
I blame Martin for being a bad influence in me in my younger days.

Cool picture with the Steiger.
It will be even more photogenic with some non black wheels!
Is Jess around? The two of you can get that top off. I have taken them off by myself, but it’s not fun.
