I was able to make room for the post bracket. It actually was pretty easy. Here is what I did after consulting IMS:
I drained the tank, washed it with water and let it sit open outside in the sun for two days before attempting to apply heat. $25.00 spent for a heat gun (with 750F and 1000F switch) from the Home Depot paint department. Apply 750F heat starting about 6 inches away to preheat and move closer for a couple minutes to raise temperature of the plastic. Switch to 1000F for a couple minutes. Press a small smooth piece of wood (could use something else I suppose but I chose wood because heat does not exchange readily and I did not think it would stick to the plastic) to tip of tank with a pair of channel locks using the bolt hole for the tank as a leverage point. Hold pressure until the plastic cools completely. Cooling can be accelerated with a cool water rinse, but I did not do this for fear of cracking the plastic. You must maintain pressure on the wood until the plastic has cooled so it does not go back to its prior shape. [IMS said the plastic has “memory” and I verified this to be true when I tried to flatten the tip of the tank by hand instead of using channel locks.] Total time including set up and clean up was about 30 minutes.
I do not know if this can be done with the stock tank, but I assume so if required.
