Do you want to fit the distributor into an early A10 or A12 engine? Or a later A12/A14/A15? The fit differently and so are not direct bolt-ins. But with simple modifications to the bolt-down bracket will fit each other.

Overview

Late engine block have a fastening bolt hole about 5mm further out from the dizzy bore hole. Plus the location and shape of the pad is different.


Early A-series (up to 1973) engines have the distributor-securing bolt hole almost straight forward of the dizzy bore hole.

Late (post-1973) A-series engines the distributor securing bolt to the rear of the dizzy bore hole.

Larger cap -- less chance to crossfire (important in humid climates)

Electronic Ignition is available too in native A-series format.

These are the normal reason one would want to fit a newer A-series dizzy in an older A-series block.


Interchange

Using 1974-up distributor in older (1966-1973) A-series engines is possible by using the distributor plate with a slight modifications to the bolt-down bracket.
