Hi David,
Thank you - we did consider a different transmission but refurbished the existing one for the moment. I will try to get the photos of the A/C installation, There have been some modifications of the ventilation system necessary such as relocation of the air vent lever and hazard lights switch that both reside under the dash centre and on the transmission tunnel so that the unit can fit in. I have attempted to attach a photo of the A/C unit in situ to illustrate but I don't think it's working.
Attachment 1859
EDIT: Not sure what happened there John, but I have added the photo - see below. Kevin.
