For the electronic distributor have a look at the complete replacement dissy called a “Scorcher” from Performance Ignitions in Australia
https://performanceignition.com.au/
It is a sensational replacement, I have had one in my SP for about 12-13 years now and I recently changed the leads, cap and rotor button just to ensure everything was in top condition, albeit it really didn’t need doing.
The “consumable” parts are all Bosch and easy and cheap to get….
