Well i have ph1 172 and i'm getting rid of the aircon, just want to produce a kit for people to just bolt on a pulley, put a belt around it job done.

Price don't know but look into things if there was enough interest will be tested by myself first and once i'm happy i would make the kits. You would be looking no more than one month before kits would be ready for people
