Sherwood's is a hack shop. Bunch of parts changers. If you need a Detroit fixed in that neck of the woods, get ahold of Penn Diesel in Ashley PA instead. They're a short ways off I-81 south of Scranton, but they've got a mobile unit that's in the Binghamton NY area a lot (mobile is based out of Syracuse NY IIRC but spends lots of time in Binghamton area).
