installing ac

I want to put ac in my car and i need to know when it went to r-134 was it 93 or was 93 the last year it was used and if anyone has done this how big of a pain was it.

it should say somewhere under your hood on the top frame bar. there should be a sticker that tell you all about the refrigerating system and what coolant you have. if you cant find it there try looking in your manual or call a local acura/honda dealer and ask.
