A few years back I fitted the Nostalgic AC aircon / heater but there was a problem.

The mountings are on sliding nuts and there is virtually no clearance on the left of the car… Once it was in that would be it, no removal short of removing multiple panels from the car which would involve drilling out lots of rivets as well as removing the panels from the sealant.

So it got shelved for a while while I mulled over the problem. Eventually I thought up of a solution. I could open up the holes and use rubber grommets with “studs” on the left instead of bolts. I opened up the holes and then hit another snag. The grommets didn’t fit as the mounting plates were 3mm and the grommets are designed for panel work, ie ~1-1.5mm.

I thought of a solution but didn’t have the materials so I shelved it again while I cracked on with other stuff.  Eventually I got round to it as I needed to buy the material for another part of the car.

The solution, delrin. I made up 4 “top hats” out of delrin, these fit into the holes as such.

These are bolted onto the AC unit like so

They’ll just slot in to the left hand side and the right will bolt up as normal. Access has been granted via suitable access panels cut in above.
