postin for a buddy.

hes got a dana 18, he thinks from an old scout, it has the texas pattern on it, and a warn overdrive on the back. the od model number is 3326(i think).
he wants to know what the overdrive unit is worth. he just got it in a trade. thanks for any help.

Not sure about the part number, but warn overdrives can go for between $200-500 depending on condition and weather they were 4 or 6 cylinder engines....check http://www.hermtheoverdriveguy.com. He seems to be the expert.
