Lovely looking car that...
Re-coring a rad is a common enough job; the top and bottom tanks are invariably kept as they'd be a custom fabrication. If there are any holes they can be filled with solder or brazed. The core in the middle tends to get silted up as it's made of fine copper pipes and the fins corrode and loose some of their ability to dissipate heat. A re-core costs me about £125 at Cheltenham radiators whom I've used a number of times.
I take it the rad is leaking somewhere then? One thing I would strongly advise against is using a stop leak prep like 'Barrs' as this coats not just the rad but the whole of the engine cooling system with a layer of crud.
I'd also add that my 164 has never got anywhere near overheating...Some 70s cars did indeed have adequate cooling systems...so the standard 2 core rad is perfectly up to scratch.
