Yeah, the balancer had slipped on the 89 and I just took the old school approach and advanced the timing too much, picked a nice steep hill, (not a problem in this neighborhood) and just ran it up the hill a few times, backing the timing off a little at a time until the pinging just stopped.
Ran it up to top dead center using the old finger in the spark plug hole method, and made my new mark.
Later on broke down and bought a new one from St. Charles, (wasn't cheap) put it on and checked it with a light and it was barely a half a degree out.
Kinda wish I'd saved my money on that one.
