Thanks!

It's also got a delay flash for checking centrifugal and vacuum advance, and a built in tachometer. www.ebay.com/itm/405606245923?Jerry

Cost? $0.00.

As I recall there's about 10 or 11 inches before you hit the distributor.

Stovebolt engines were designed to use a plain old ice pick type test light to do a perfectly adequate job of setting the spark timing.
