Ford Mustang T5 Transmission Needs Rebuild - $500 (Seymour)

Used T5 transmission, last used in a 1987 Mustang GT.
Needs rebuild.
I can't remember which gears are toast; I replaced this in my Mustang at least 10 years ago, and kept it assuming I would rebuild it someday.
That project time will never come, so this needs to go.
Best reasonable offer.
Would definitely prefer not to ship, but would consider it at buyer's expense.
