True HEI distributor conversion thoughts

Mopar Chrysler SB 318 340 360 Ready to Run Electronic Distributor (Vacuum) Hei | eBay

this is basically the same but you will need a 12 volt coil to go with it....E coil

Certainly will not have the clearance issue
This is the setup I'm running on my 68 Barracuda 318.....
Works great and fit no problem.
