I replaced my clutch recently and was conemplating buying a flywheel lock with all the other parts I had to get. But before I did was down at Ace Hardware and saw this metal plate. I thought it would be just the ticket and it was. So for about a dollar I bought the metal plate and a bolt rigged up a perfectly working flywheel lock.
So if you need a lock and want to save a few bucks give this a try. By the way the bolt on the left is an extra starter bolt.
