Bellhousing question

The 1967 273 3-speed used a small 9 1/4" clutch. The bigger engines used a more standard 10 1/2 inch clutch which is what most V8 cars used in the later years. The smaller clutch used a 122 tooth flywheel with a smaller bell and release fork. If you put this back the way it was, you will need to find all these parts. I have a 1967 Barracuda with the small clutch and parts are getting difficult to find. It is much easier to find parts for the more standard 10 1/2 inch clutch. I don't think you would have a problem going to a 10 1/2 inch clutch in your car. You will need a 13o tooth flywheel, pressure plate, clutch disk and release fork. Everything else should be the same.
