By Anonymous Hi, This is my 4th attempt to get an email response on the following. I have a 1964 Buick Riviera with 2X4BBl carb. The stock air filter may not clear the front two dist spark towers of the 8524. I measure about 7 7/8 to the bottom of the air cleaner. Your spec is 8 3/8 tall to the top center tower. What is the distance to the outer spark plug towers and would yor GM replacement cap give me more romm (and work) in this application? Thanks Tony Cucinotta 817 691 6634 tjcucinotta@earthlink.net |
