All. Just a quick note, before Gaydon I had my air-con system re-filled. I went to a firm near Manchester called 'Airconco', they can be foud at www.airconditioningcompany.co.uk They use a drop-in replacement called RS-24. This requires no modifications to the DeLorean and is designed to work well at the lower pressures (2.2lb/~1.25Kg) specified in the service bulletins. They do a lot of work with classics and commercial vehicles which run on R12 and were very complementary about the DeLorean layout for measuring the compressor oil etc. Complete unload of my original R12 charge (<300g), pressure test and reload took ~45mins. Cost was £78 inc VAT and a complementary de- odouriser spray. John Chapelhow DOC 19 : 'Boeing' 0737
