Mauro,
As you seem to be always gogin on about wanting it stock, then modfied but
erversable.. you need to be clear as to what your requirements are. Theo is
on the money as to what he said..
If you want a distributor go to electronic..
Choose between optical and magnetic
Choose if you want a more powerful spark
Choose if you want a controller crane Hi6/MSd etc
or to keep stock appearane get a petronix or lumention etc that replaces the
points in a stock unit. that will look the most correct.
