I have an axial compressor that was only used on the 74 coupes and 3.0S and Si sedans from 74 onwards and which uses a pretty unique bracket. It is being rebuilt by Jay Stratton and he did another which is now in my e12. They were also used in the e12/e24 through 1981 only. Parts are very hard to find especially the fiber ring which is NLA and must be removed to replace one of the bearings and it often breaks. My e12 is now blowing nice and cold using r12. Send me a note if you would be interested in this rebuilt compressor. Thanks
