replacing the stock contact breakers that cannot be properly set up.
what am I wanting to achieve? accurate ignition timing, no re-gapping of the points every couple of months, cursing because they cannot be advanced or retarded enough to maintain the specified dwell.
that kind of thing...
the sachse so far (1000+ miles) seems to perform these jobs admirably. However, as stated in the OP, I have to shim it quite a bit to get the disc to clear the brush holders, which doesn't seem right to me... means you then have to shim the alternator cover to clear the disc which leaves a fair gap which again doesnt seem right...
