R12 Refigerant replacements Freeze 12?

My Auto: 88 300TE
Subject: R12 Replacement
After some analysis I have found some R12 Replacment Refigerant/Lubricant combinations ie: Mc Cool, Freezone, Freeze 12 have mixed reliability with the rubber seals ie: some work well with Nitrile others work well with Neoprene (for more information on this do a search on http://www.santech.com/Testing.htm

Only R12 and R134 have complete reliability.

Anyone with experience here?

Thanks Tom Craney
