Not sure if this is the right place, but does anyone know of a "kit" of all the correct o-rings for the A/C system (69 440)?
Or us it just by an assortment of modern metric ones and make them fit?
Harbor Freight sells the plastic case set of o-rings. Are you still using R-12 or did you convert to R-134? Either way, they sell both the black o-ring and green R-134 seals.
Here they are: https://www.harborfreight.com/search?q=o-rings
Bottom right, you see the green R-134 seals. All these sets are under $10. Use the 20% off coupon for these.
