Two stainless screws from a different tank screwed into two opposite holes and then ground down as flush as possible not pretty but works.
Installing a horizontal coil was not to bad , have to change cotton more as it just goes thru the coil only not placed in there like the original vertical coil design.
Almost gave up on it when it kept flooding etc then decided to close off 2 of the holes on a whim and all of a sudden it worked just fine go figure.
After 4 months of use in rotation with cotton changing this setup is still working just fine no leakage with DIY e-liquid that is about 93% PG .
