This is a special advance unit for the Delco D204 distributor. It’s not original. Made from Delco and Lucas parts.
This unit replaces the later retard units to change to vacuum advance.
Also most carburettors need to be machined for ported vacuum or it will not operate properly. It also needs to be fit to the distributor. One screw hole needs to be drilled and threaded.
Please note: The customer needs skills.
This is a fix for the NLS retard unit and customers who want to use vacuum advance.
