[quote quote=14172]So I found a TH200.. The seller gave me the tag number 84-01-13245, and I think the casting number 3fm320825. I have searched all over , and cannot find any info. Anyone?[/quote]
3FM320825 is the VIN derivative.
3 = Oldsmobile Division
F = model year 1985
NOTE: the other tag indicates a 1984 model year. Are you sure this is an “F” and not an “E”? E would be correct for 1984.
M = Lansing assembly plant
320825 = last six digits from the VIN of the car it came from.
