Father-Son 1974 Duster Project

I need to find out what kind of bolts to use to bolt the flex plate to the torque converter....

We bought a nice stock gently used radiator from a V8 auto trans AC 74 A body. It's on it's way to us now.

Our distributor arrived today and I'm wondering if I should just use the Chrysler ECU box and ballast resistor since our under hood harness is in tact. I really think going with the HEI module would be better for our purposes.

I'm wondering what do you do with the unused connector on the harness that is for the Chrysler ECU box if you don't use one?

If you need 4 bolts I will send them to you free, just pm me.
