I successfully repaired a small crack in the neck/radiator seam using
epoxy. That was on a TR3 where an R&R of the radiator is a bit of a
PITA -- so much easier on a 4. However, if you want to try the epoxy,
here is what I did: I got the coolant level low enough that the joint
was dry, cleaned the joint then got the engine well warmed up. Engine
off I applied the epoxy (radiator cap in place) and hoped the slight
vacuum created by the cooling coolant would draw the epoxy into the
crack. Maybe it did, maybe it didn't, but the leak has stayed sealed
for many years.
