thats what I am doing in my 55 1.5T berad truck.. originally had a 261 and the same 4 speed as mentioned above.. you need the 55-64 bell housing as they went to a bigger bearing retainer in 65. the flywheel wont work.. need one of them too.. also you can run your original friction disc. but depending on which flywheel you may need to get a different preassure plate. the fork should swap over as well..
