My attempt on this would be:
- Keep all AE86/4AC bits of aircon (condensor, lines, in cabin box, etc, etc)
- Use the 4AGZE compressor on the 4AGZE cast mount (on passenger side, in the middle, below PS pump and above alternator)
- See if any of the lines you have suit to connect the 4AGZE compressor to the AE86 lines. If not, get some custom made.
