most trucks got the same option number for 350 or 400 tranny as mentioned above... M49. A small handfull of trucks got mismarked M38 for the TH350.
Some will tell you the M49 was a TH350, and the M49* was a 400, but I call BS on that one personally.
And for the nay sayers, TH350 was avalible on 10, 20 and 30 series trucks, not just the 10 series.
