Quick question- Shifting to the pertronix system.
The Dizzy has "25D" stamped on it.
Would 25D4 be the same?
Harry
 
Yes, if it is a 4 cylinder version. 25D6 is 6 cylinder.
 
As Randall said, yes... 25D is the shape/type and 4 is for 4-cylinder. For a TR4 with negative ground you want LU142A. If your car has positive ground it will need LU142AP12. Shop around for the best price available. When I last bought one the best price came from Retrorockets (online). You can find them by Googling for "retrorockets pertronix".
