10 inch AFB Air Cleaner Base Plate

To clarify, do you need the base from an AFB with a 4 11/16" flange? Better check your carb number to verify, and check the throat size! The book lists a 4119, 4120, 4121 and 4122 for 1966, and 4294 and 4295 for 1967! Not sure if the 67's had the 4 11/16" throat size but I know the 66's did! Here's a pic of a 66 unit, measures just over 4 5/8"!
