I'm in the process of rebuilding a '87 2F and I'm trying to decide if it would be worth it to replace the clutch or not. I have a clutch with 50K Miles and seems to be in good shape. I also had the flywheel resurfaced. I'm over budget because this project started as a '85 2F, but that motor turned out to be hatched, so I had to buy another engine. Is it worth it to replace the disc and/or diaphram?
