YES! And I promise you that you will be well satisfied. My '87 124 was converted to 134a by a previous owner & after suffering through one summer of way-less-that-cool AC I re-converted to R12.
As suggested above, use the search function. Also, as recommended above, you WILL need a set of gauges. Keep in mind that the gauges for R12 are different that those for R134a (I think). They can be had for minor $$$ from EBay, Craigslist, local pawn shops, etc. The set I bought for $15 is worth its weight in gold to me.
Posts by LarryBible, VSTech are the most informative & accurate. Be aware that there are a lot of "shade-tree" AC repairers out there that may lead you astray. But those two guys have forgotten more about auto AC systems than most remember. There are also a couple of other guys that give good info, but can't remember them right now.
R-12 is not as expensive as many people think & it is what your car's AC system is designed to use. If you just want to get by for the rest of the summer, use 134a. But plan on "upgrading" to R12 as soon as you can. There is no way I would ever go back to R134a - I would almost as soon do without AC (might as well, it's performance is about the same).
