Magneto Impulse Coupling Adapter Question

[RobinHou]

We are a 501c3 nonprofit organization. Our club's Pazmany restoration project is using an experimental Lycoming O-290. Its old mags have shower of spark. We have no history of these mags and some parts are missing. We also don't have the buzz box. The costs of overhaul and missing parts lead us to consider buying a set of new mags. So we ended up with a set of lightly used Slick 4371 at great price. 4371's are impulse coupling mags.

We are now in need of a set of Lycoming impulse coupling adapters. They are plentiful on eBay. However, I am not sure if we need the Lycoming LW12706 or LW 12707. What is the difference between these parts?

Any information to help us getting the right parts is greatly appreciated.

Thanks in advance.
