I forgot to mention what ever transmission you get you also need the correct flywheel. They all use a different one. I hope when they rebuilt your engine they put in the double lip crankshaft seal. No big deal if not as you can change it easily when you replace the flywheel. Just check the part number they used. Double lip is 8927749. Single lip is 5114335. Single lip number might update as my numbers for it are very old. Double lip is current.
