So far, I haven’t run into many complaints or issues with Davis Unified Ignition parts. They do sell a cap / rotor / coil / module ‘kit’ for those that have a solid factory distributor. They also sell those parts individually.
Granted, I don’t put a ton of miles on my cars, but I have a pair of complete DUI HEIs that have been in service for 8+ years with zero issues.
