2.4 distributor has a disc & reader, same as a DSM CAS. Nothing like the earlier or starquest VR type dizzy
Those are compatible with basic megasquirted starions, and MSD.
They lockout (=wire tie posts and remove the vacuum cannister, to fix timimg).... so the ecu now controls ignition curve
some 2.6 starquests run the 2.4 distributor, but requires a 6mm spacer
