Not sure what you are specifically asking about this dizzy but I take it that looks are more important then money for your build.
The Dizzy itself would be a plug and play with a GM TBI system for running fuel and spark control. Wouldn't be good for a fuel only system like the Howell that most on here seem to run.
The standard DS distr conversion can work just as well but may not be as eye appealing to some. Just make the mounting plate as part of the vacuum advance cover.
