AC-Delco part number D105P or D111 is what the 235's use.
On EBAY, you can find the original foil packaged ones, or NAPA has Echlin brand, # CS763A heavy duty points set. They sell five different sets of points that interchange with D105P, the heavy duty is what I would use. The foil pack ones are the original ones, the box sets are later ones, you can get them local. They won't be the same quality.
