I am currently putting the same unit in my '53. Check the input shafts of your original trans. and the OD unit because the car OD units have a smaller input, shorter by approx. 1" and smaller diameter. My truck bellhousing has the rear frame mounts and my trans. does not have a mount at all. My trans. and OD unit will just hang there. Parts can be found as this OD unit ( borg warner R 10 ) was put in cars from 1938 to 1972 and all the internals are interchangable. There is an R 11 unit that was built in the 60's and up for larger engines but I don't know much about them. Also check the side case of the 3 speed to see if you have the threaded bosses that the clutch pedal shaft plate bolts to. If you have to swap these, be carfull to replace the reverse lock out cam that activates the 1st/reverse shift fork. Without this, a mistake could clean house in the OD unit. For the price you quoted, I think you will have a very nice correct looking OD cruiser. Jeff.
