I wanted a new one when I put the ZZ383 in, so:
I bought a GMPP complete distributor. $260.00

Found out it DID NOT have a adjustable vacuum advance . So bought one. Accel. $34.00
Found out the coil on it was garbage. It took out the module. So bought Accel coil and module. $70.00 and $60.00
Lesson here is don't be like me.....and have to spend like $ 450.00 for a stupid HEI
