This is a coolant leak right?

If you want to SHOP to see what is available, check out summit racing. They have several brands and types of radiators to choose from. Then after seeing what is available, use the part numbers to source the type you want locally. We bought a brass radiator from Summit and it worked and fit great.

Look I'm not talkin chit (much) but you could have fixed it that day - A WEEK AGO.
Ye olde radiator repair shoppe and them "good olde days" are long gone even though the truck remains.

You're the only guy that is gonna make it easy on you..tryin to help.

Evidently, the good ole days are still alive and well where I live.

If you can find the leak yourself there's some radiator puddy I got from Walmart or parts house that works really well. I put it on the 82 and it has held up well. I was gonna buy a new one but tried that first and it's help up ever since. Just another option for you. I'll take a picture of it when I get home if you want me

Thanks for the info, I think I’m leaning toward this option. It’s really difficult to tell where the leak is coming from with the fan shroud installed. I tried unbolting it at the top, but that’s still didn’t really give me enough clearance to see much. Is the best approach to pull the radiator and pressurize it and hit it with snoop to find the leaks? If so, what is the best way to pressurize the radiator and to what max pressure?

I’ve been looking at a lot of different sites and I guess what so confusing or all the many varying opinions about aluminum versus brass, etc. Ideally, I don’t want to spend $400 or $500. Seems like Summit and champion have some good options. I want something that’s reliable that isn’t gonna leak again while I own this truck if I do invest in replacing it. I don’t need the best of the best but I want good quality and a good value.

Mine was right where I could get to it without having to remove it. You should be able to shove the fan shroud towards the motor and slide the radiator up and out after disconnecting the hoses and transmission lines. I think it wouldn't take much pressure to get it to leak. Maybe 25 or 30 pounds of air. Soapy water should work. I'll take some pictures of it when I get home from work.

This is what I used. It should work. I just globbed on some and pushed it on And let it harden. It works even if it's a little wet. I probably used a little more than I needed but it holds.

Is what many car youtubers are doing, you know that means a bit pricey.

Awesome, thanks for all the pictures and information. Looks like I’ll be pulling my radiator this weekend to try this. Thanks for your help.

Took my 86 rad to get it fixed, but was bad corroded, many tiny holes. Your truck looks like it does not have air, so very easy to fix. I bought a new rad through the shop that I took my radiator to, about $570, but with care, should out last me.
