The low profile Offy manifold has been on back order since 1988. Try it and see, though!
If someone can measure from the inside of their hood to the top of a stock manifold with no carb on it, I can do the same and let you know if there would be a fitment problem with the taller profile Offy. I am GUESSING that there would be a problem unless the air cleaners are really low profile.
(Take two empty toilet paper rolls, put one inside the other by putting a small crimp in it. GENTLY close the hood. Open the hood and measure the height of the two rolls.)
