Let’s see if Jeff, 2112 or GT@50 reply, as they are in Seattle. Rob Henderson (GT@50) owns a transmission shop near Renton where you might have it inspected.
Happy to go look at it if it can wait until 12/11/21 or later. I'll be in Hermosillo. Anybody need anything there? I have the GT figured out but couldn't tell you much about a '38 Bugatti other than fit, finish, workmanship, what I see.
