A question On the pertronics unit, I read if you replace the points with this unit you have to retime the car, is this true ??

Yes, changing the trigger device requires a timing chk.
Especially point to electronic.
Where the points may have fired the coil at say 14 degrees, the replacement unit could fire it at 8, or 20 who knows.
