Haven't had time to mess with it this week, but last night when I got home, I got out teh flashlight. Looks like, in addition to teh cap issue, the left side if you are facing the grill) is leaking around the fins.
Now that your cap holds pressure, some weak links can appear in the radiator.
If it is just a couple of leaky tubes, as Barry said, a radiator shop may be able to do an affordable repair. Sometimes they will just "pinch off" the bad tube cutting it and soldering the pinched ends and eliminate it from flowing coolant.

I have a brass radiator in my '72 GMC that was in a race car back in the early 1980s that the fan hit. There are probably 7 or 8 tubes pinched and soldered and it has been in my truck since around 1989!

I am probably going to break down and order the one in this Amazon link for my '55 GMC. $220 free shipping. There may be some radiators on there that will fit your truck.
