transmission adapter 1933 Dodge with 1953 230 Flathead 6 - TRANSMISSION HELP NEEDED

[Mopar-Boy]

GREAT thread.  Does anyone have the dimensions of the bell housings front to back, gear box front to back?  I believe from other thread here, that Don Coatney milled the starter mount to make the gears line up.  I have both a '33 3 speed from a dodge dp6 and a 3 speed (fluid drive) from a 49 coronet.  Both are functional.  I definitely would like to keep the original 1933 tranny and drive train.  I actually really like the brake handle engaging the parking brake on the trans, AND I would prefer to make the stomp starter work.  I understand that the offset for flywheels is different, but can I bolt the 1933 tranny, bellhousing AND starter right up to the 1949 230?  If so, that would be FANTASTIC!  I will find out eventually, once I'm ready to pull the 201 and attached tranny out and can measure everything.  Hoping someone just "happens to know".  Thx in advance.

The critical measurements, input shaft length, (fluid drive equiped cars have a longer shaft. Crankshaft flange thickness (fd are thicker) input shaftcarrier bearing diameter, will it fit into the hole in the bell housing, and input shaft spine count.  The spine count can usually be dealt with by installing thematching clutch friction disc.  And if the stomp switch is mounted to the bell housing are the mountings comparable?I have a 46 transom the garage but I don't know if those measurements will help you.

 

There also may be an issue with the flywheel pilot shaft bushing diameter.

Thanks Greg G.  I will actually photo, measure and post the metrics while I have both of them side by side.

when you swap the trans what are you guys doing for a parking brake since the original is on the transmission?

update: I rebuilt my 230 flathead six, installed a George Asche 1939 Plymouth 3 speed with overdrive that kept the shifter in the stock location. , and custom built a long 90 degree bar that worked with the stock E-Brake.
