Can I retrofit a 94 with a cupholder-armrest? Options

[ChrisH]

I just bought a used 94 Celica ST (automatic transmission), and discovered that it has no cupholders for that model year. I want to add cupholders. I searched the threads here and saw some people added DIN cupholders to the dash, but I am concerned about condensation dripping onto controls lower down the center console. I am considering other options, such as retrofitting with a later year's armrest cupholder. My transmission is an automatic, so I am not as concerned about the position of the cupholders effecting shifting (like the manual transmission people care about).

My question is, can I just get a later year's cupholder-armrest and simply replace the armrest on the 94's console, or do I need to replace the whole rear center console? I am concerned that the hinge, latch, and/or notches in the rear center console for the years with the cupholder may be different than the 94 without the cupholder.

I examined my armrest more carefully, and it is apparent that the cupholder tray has been removed. I'm guessing the previous owner broke it and just removed it. I'm going to replace it. I already found a source.
