If your distributor number is 2875334 then it is from a 1968 273 V-8. It is a Chrysler made distributor. .017 gap [28-32 dwell]. Any used 318 or 273 vacuum advance unit should work. Polish your 8 sided dist. cam with 600 or 1000 grit paper. Use a little dist. cam lube on the cam. About 3 drops of light oil into the felt pad under the rotor. Free up the weights under the points plate and lube. When working properly, the rotor should turn about 1/2" in one direction and then spring back to where it was. This is done with the dist. shaft held in a vice.
