Kerry , How do you figure a dehumidifyer works ? LOL
Sdelasal, You can put your location where it shows on the left by your name.... that will explain somethings without an extra post...
123c, Well, with that good short haircut you sure won't have to worry about the wind messing up your hair...(mine is same way)
DieselHead, you could go on the internet and pay about $15 and take an open book test for your r12 license.. then buy it from anyone on Ebay ... or find a local dealer....

Sdelasal, The conversion kits should be available from any auto parts store... there is not one specifically for your car... just fits any R12 system... it involves flushing your system, putting new reciever/dryer in , screwing the new quick connect valves on the top of the Schraeder valves, being sure your oil in your compressor is compatible with the R134 , and has the right amount, ....and be sure to only fill the system to about 85% the weight of 134 which you would have put R12.... but I do think you need to have someone experienced pull the system to as many inches of mercury for several hours as possible... to check for leaks and to get the moisture out.....then you need the 134 gauges to install to the correct head pressure.... You may can rent vacuum machines.... and perhaps the guages... (?)...good luck... I would not mess with the ac system without first obtaining a MB factory shop manual for your car....
