Weil-McLain sells boilers and parts through local plumbing/heating suppliers, call them for a replacement.
However, rust and age can make it difficult to change the coil without damaging the bolts to hold it; making a leaky result.
The more usual way to make the fix is to cap off the coil connections, leaving the coil inside and adding a separate indirect heating tank. You also get more hot water at better efficiency that way.
The other is to replace the boiler with a newer one with a tankless coil that is more efficient as well.
