To all you Buick Guys,
Thanks for all the responses. Last night I was using KN's search by size, so I should at least find something that works. I'm going through all responses right now. Now that I know more I can add more. The air filter housing is a pancake type. The chrome cover fits exactly over the air filter. The pancake housing is 16 1/2 ins. in diam., and the chrome cover is 14 1/8 ins. in diam. The carb is a Carter Thermo Quad with the following #'s on the top-rear of the carb, "6-2141" with an "11" just after and above the 2141. I've tried attaching photo's but not having success, hate to ask, how to attach? Again, thanks for all the help. Richard
