I am building a 1930 Model A coupe with a 39 Ford Flathead and would like to run either a Richmond T10 or Super Street transmission. Do Offenhauser offer adaptors for either of these?
You can use Offenhauser adapter number 5272 or 5174. 5272 uses flathead Ford clutch release shaft and throwout bearing while 5174 uses the GM clutch release shaft and throwout bearing.
