[DeTomaso] R 12 conversions

[zumzum at cox.net]

Boyd,
Changing over 12 to 134 is no big deal. My shop does about three a week on Benzes, BMW's and Toyotas to Hondas.
I understand that your are not a mechanic but keep in mind that your life will be better if you just fix it now and
think about it for years and years and years later while you are in the cool. Get over the scare of chicken little.
Have your mechanic do it the correct way and no problem will happen. Too much thought stops a good job, not enough action.
In 2004, I put 134 in a customers Honda Accord without changing the drier or oil as a test, expecting the worse. Just adaptors and 134.
Still no problem, the sky did not fall. I've owned my shop for 29 years. Too much bullshit hype over a gas made for cooling.
I am in Louisiana and our a/c's are important.
Just get rid of the mineral oil, use ester and vacuum and charge. Sell your cans on eBay.
Take care
