Looking for a Spa model# or type

I have a spa that was purchased at the Regent Aquatech in 1999. It has a 1997 date on it, was a floor model and didn’t come with a manual. I’m trying to replace some jets and the pillows, and I’m trying to find what type of spa it would have been. It has the Aqua Spa Pak 2000 ProSeries in it. There is 14-16 Jets in it, and was a smaller tub. Any place on the tub that would tell me this, or any idea how to determine what jets would fit (or how to remove them!)
