GMC'ers,
Don't throw away or replace that old HEI unit. They're rebuildable. GM
P/N 1894379. This is for a replacement shaft kit that includes
bushings. They're about the only parts of the unit that can wear out.
If you're worried about the advance curve, send the whole thing to GES
engineering here in San Diego. He will professionally recurve yours, or
your replacement, and install an adjustable vacuum advance kit. Runs
around $100 plus parts. He'll also provide the curve specs. He also
rebuilds/recurves older points type units.
