There's a good thread on thesamba.com about using Red Tek for conversions. According to those who have used it, it cools better than R134a and is available direct, I think. Since my own backyard R134a conversion does not cool wonderfully, I may try this when I do the more in-depth fix with new seals and the new receiver/dryer.
