Glad I was able to help.
I also agree that the "Power Tower" pad one is also different.
When the Power Tower was produced, both Centuri and Estes were owned by Damon.
The Power Tower was a clone of the Estes Porta Pad.
The only thing that differentiated the two was color and blast deflector shape.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
