Thanks Joshua,

Just found out I needed a new compressor the other day but unsure what exactly to do. This makes it much clearer, going to order my kit from original air tomorrow. 1981 C10 305

One thing I recommend is trying out the blue Orifice tube. I went with an OEM white one but with a switch to R-134, I think the blue would help a lot better. Might get you a few degrees colder.

Hell yeah Brother!! I just did mine on my 84. I was lucky and had a system that hadnt been open so i just bought a drier,o tube, compressor, and flush. Already had new lines, o rings, and refrigerant. Also already had a r4 compressor setup from stock so score there...

I like that bracket....looks beefy. I modified my oe bracket to work with my headers but I eventually plan to go all billet.

Yeah, really happy with the original air bracket. I have a 60” belt and I think because of the bracket adjustment, it can fit anywhere between A 59” or 61”. Good luck and let me know what temps you get out of the vents! Also, you go blue o-tube?

stock white $2 orifice tube. 51deg sitting still on a 96deg day in alabama... so extreme humidity. It dropped noticeably while driving though. Had condensation after 2-3 minutes of driving so id say somewhere near 40ish degrees. I didnt measure while driving though. It will freeze you out of the truck on anything but low after a minute or so.
My brother always comments on my Nissan factory ac being the coldest he has felt....my trucks is colder imho.
Ive always thought it was pretty easy for these large systems to cool the single cabs. Same system on the suburbans and k5s and they do (OK).

2 year update. This thing is freezing me out while on the highway. Temps around 45 on a summer day medium blower speed. Will get colder on lower Fan speeds

I know it's been 2 years but do you remember if the o-ring kit had the one for here (your pic)?

I got some and this one was too big to fit into the shoulder are and I am worried it's going to leak.

@Scott91370 Either it came with my drier or was in that kit.

How much oil did you use? Also around how much r134a I have an 85 K5 Blazer with r4 on the driverside with v-belts. I HATE THAT R4. Have you heard any who did this conversion with OEM PF condenser?

Update on the kit from original air has almost doubled to $1350.

MUCH cheaper to buy the kit yourself and you’ll get hoses as well!
$714 not including some R-134. Here’s the kit I was able to put together. Hope it helps.

Vintage air #04808-VUA From Summit $222.00

Original air bracket $155.00
There are cheaper bracket options out there. I liked this one because it kept the compressor closer to engine and was beefier.
