not sure how aftermarket dizzies are, but stock fox dizzies have the TFI on the dizzy itself, as opposed to the fender. one could work around that (from what i have been reading/researching, one can procure a harness from a van which can allow a fox to remotely mount the TFI).
:OT: John congrats on graduating! We were down at the TCC on Fri - what a zoo. LOL. (did not go on Sat).
