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.

May i add that regardless of the messy car, and the HUMONGOUS chiwawa animal, That the cupholder itself looks pretty good. I've seen it first hand, and it's got such an OEM quality to it, that it had to be pointed out to me when i was already back there.
