O = 8-78 (date, built August 1978,) wonder if the cast number is a 78 instead of 79 ?
M = Built at Mound Road Plant
318 = Self Explanitory
04289587 = Have not figured this number out yet.
Thanks!! I believe its a 79, it came out of an 1980 Volare Roadrunner, but it could possibly be 78, its incredibly hard to read the last number, same as the 04289587, i could be off by a number.
