I doubt you'll find a Lakewood since they haven't been made in a very long time.
The Quicktime bells are available. In a clutch fork application, you may have a pushrod alignment issue, but as Jared says, it's not too hard to make them work. There is also a newer RM-6057 available with an 8:00-9:00 clutch fork position. It's about $20 more.
