Wiring Suggestion/Help

On our '68 Bcuda Convertible build, we swapped an older 225 with a point ditributor to a '74 with an electronic distributor. Now we've realized the new brand new wiring harness from Classic Industries for the '68 doesn't work for this and looking for anyone's experience/suggestion whether we can mix-and-match or should should splice? Either way, what other electrical goodies might we need for this regardless of the wiring path we use?

Does classic have the Electronic ignition pigtail that you can add to the 68 harness?
