They don't make anything per se, they just make it easier to fit and wire IMO.

I'm using:
Supertec twin-plug distributor with a magnetic pickup, but fitting an early case
2x MSD 6AL boxes
2x MSD High vibration coils
MFI Connector to spilt the green signal wire into the 2 MSD harnesses (Green / Violet wires)
Magnecor plug wires

Going a bit further, it's being used on a 2.6 with:
Early aluminum case
92mm P&C - NOS Mahle
S Cams
66mm Counter-weighted crank
40mm Webers

The twin-plugging wasn't a cheap option, but when compared to the cost of some of the other stuff, it wasn't too bad!
