I'm just wondering while choosing a flywheel for the subaru conversion if there were any major differences in flywheels over the years of type 1's. I have the flywheel from a 71 super and a couple from the 60's but they are still in the cars (parts cars). anyone know the differences/weights? I'm figuring I'm probably going to want the heaviest one if there is a difference. Thanks
