A round here a product called "Freeze 12" was the solution to the need for R12 in older vehicles. Most people who are in need of the air conditioner in their older vehicles now bite the bullet and retrofit to use the R134a.
The one I mentioned and the one you mentioned (claim) it could be installed "on top of" the R12 without clearing the system of the old oil (more work)
I have a link to the one you questioned
Their ad says it is compatible, I do see that they have adapters for the fill/ test ports so that the newer style hoses/ gauges can connect to the old style ports
Yep, I would give it a shot myself.
