60's air condtioner hose

I've probably asked this before but perhaps things have changed. I need to find modern air conditioner hoses that are suitable for R134 but look like the old woven fabric hoses of the sixties for my Mistral. Many of the cars of that era had the woven fabric cover but in searching the internet I have found no modern replacements. What is the restoration industry doing to replace the old hoses, given that R12 is no longer viable and the R134 will leak through the old hoses as they are not of the barrier type. For authenticity one needs something that looks like the original type but is suitable for modern day use. Any suggestions or leads would be most appreciated.

 

Unfortunately, I really don't want to use R12 even if I can source it. I know that sounds kind of "green" but the old R12 was phased out for sound reasons. That still leave me where I stated in my previous post. Is there any substitute that looks like the old hose but meet modern standards. What happens to some of the very valuable older cars when the old hose needs to be replaced, for any reason, and the concours judges see modern hose. What will the top tier restoration people do to maintain the proper look and what if the judges want to see if the air conditioning works and someone has chosen to keep the old hoses but deactivate their air conditioning system because they either don't have R12 or don't want to use it for environmental reasons?
