I have just located some NOS distributor housings (p/n GT-121 Generator Ignitor Housing Extensions) for the 1928-1929 Durants with Continental 14L & 15L engines. These are the right angle drive housings that adapt the distributor to the end of the generator. It turns out that these were used up into the 1960’s in an industrial application and I have come across a few that were left over in a dealers inventory. Price is $195 plus S & H.
