My Version

Parts: Large Cap HEI distributor from a chevy I-6 truck.
Ignition Module for an 85 Corvette ($15 wells brand from autozone)
.110" female spade terminals. - I got mine from a custom car audio place
You'll want wires for the chevy truck, or a 1980 ford f-150 with the i-6 300.
New Cap, Rotor, Coil if you like.

How to:

Pull the cap and rotor off the dist. Remove the advance springs, weights, and the center piece between the weights. Remove the Ignition Module and coil connector with noise suppressor. Remove the Vaccum Advance. - see options below. putting it together Vaccum advance elimination option 1:
CAREFULLY bend the tab that connected to the vaccum advance out so that you can screw it down to the boss that the vaccum advance used to connect to.
If you break the tab, you'll have to replace the pickup, so be careful. Vaccum advance elimination option 2:
Tack weld the advance pull, cut off the vaccum chamber and reinstall it.
Vaccum advance elimination option 3:
Put the advance in and just leave the hose off or cut off the hose connection.
Centrifugal Advance:
You already pulled the bits off. Just connect the upper plate with the lower plate with either a piece of metal or something similar.
Igniton module:
place the new ignition module where the old one used to be, note how the two tabs line up and go in place, but the mounting holes don't line up.
Drill and tap new holes. It's a 6-32 tap and you'll need a #36 or a 7/64 bit. This way you don't have to modify your ignition module to mount it.
Distributor Gear:
Get the correct gear for the 258: either NAPA BK655-1284 for an 85 grand wagoneer with a 360, one off a wagoneer junkyard V8, or whoever you like. Replace the old one with the new one and be done with it.
wiring:
cut off the old pickup unit connector as close to the connector as you can. Install 2 femal spade terminals on the pickup leads. These connect to the two terminals labelled N and P on the igniton module. You can reinstall the coil noise isolator whenever you like.
For the connector to my EFI harness, I'm using a 2 pin weather pack, and a 3 ping weather pack connector. The 2 pin will connect the ground and the hot coil lead to the dist, and the 3 pin will connect to the B, R, and E connectors on the ignition module.

You should now have a computer controlled distributor for the 258.
