tune up questions

[wellcraft]

Does somebody knows what parts I should replace to do a full tune up on this cars, does anyone has the part numbers for each one? Been trying to find this info with no avail.
Woild this be orrect to replace, distributor cap, rotor, sparkplug wires, belts, anything else (do they have points, condenser or some ignition parts I should also replace)? By looking at the cap I would assume that could be the culprit of my small hesitation. I added a bottle of seafoam to clean the injectors.

Thanks in advance.
