Congrats on this Jon - sounds like it was a bit of a journey to get this done but super happy to hear you were successful. With this new centerpost and plastic tub this is going to last a very very long time!
Curious in case I ever have to do this in the future, what did they use for the replacement centerpost and what were the dimensions if you don't mind sharing?
Congrats once again and can't wait to see the final product
