Mike,
Try to not reinvent the wheel here....!
The DuraSpark II system, albeit with a few extra parts to be mounted elsewhere, fits along with the stock air cleaner, looks basically stock, and it works.
Or simply put in a Pertronix....also works.
Your car is not a race car, never will be. IMHO, the HEI offers nothing but problems making it fit.
DO NOT cut the stock air cleaner what ever you choose to do.......
Your car is a rolling piece of art! It can roll reliably without defacing it.
Ciao!
