UPDATE: In the end I've decided to buy the black crackle-finish
"Cobra" air cleaner and matching
"427 Cobra" pentroof valve covers from Ford Racing.
The pricing on these items from our local Ford Racing dealer were simply too good to pass up (below MSRP and in CAD no less), far less than buying the reproduction air cleaner alone from Branda or anyone else (see above).
And although I really like the authentic turkey pan/
chrome pentroof valve cover look, I can't justify the expense.
Thanks to everyone who provided me their advice and suggestions.
