I installed two custom made hoses ordered from Ray at:
http://www.rayeveritt.com
to replace two which were leaking (one had a pinhole and one was leaking at the crimp-fitting). For $50 I got both custom hoses made up and put them in this week...then I transfused a load of R12 from my 560SL which is presently giving me AC issues and the '64 is cool again. If you need custom AC hoses I recommend Ray Everett...fast service and good quality.
