5ktq radiator repair?

[Steve Arbaugh]

My ’86 5ktqw is apparently tired of it’s radiator and wants something done
about it. The seams are starting to split right by the upper rad hose. It
appears to have been in the car for quite some time, has metal (alum?) caps,
metal tag on the top. Are these things reparable or is it better to replace
them? What has been the collective experience? If replacement is the better
course, any suggested sources?

Many thanks..
