BOLT PATTERN FROM CENTER TO CENTER IS 42MM.
 
THE 1969 TO 1977 HAD A 48MM BOLT PATTERN

THIS CARB IS THE SAME AS THE CT70 78 TO 82 EXCEPT WE RE-JETTED IT AND MADE SOME SLIDE NEEDLE ADJUSTMENTS. BUT THERE ARE SOME DIFFERENCES FROM THE ORIGINAL KO TO 77 CT70 CARB, BUT THIS WILL WORK!!! GREAT!!!!. ALL YOU HAVE TO DO IS NOTCH YOUR INTAKE MANIFOLD HOLES CLOSER TOGETHER, AS THE BOLT PATTERN ON THIS CARB IS ABOUT 7MM CLOSER. THIS CARB IS SLIGHTLY SHORTER FROM FRONT TO BACK SO IT FITS BETTER IF YOU GET THE NEW CARB TO AIR CLEANER BOOT AS THIS BOOT IS SLIGHTLY LONGER THAN THE ORIGINAL ONES ON THE CT70KO THRU 1977.
 
SOME PEOPLE WILL NEED 2EA OF A 6 X 25MM BOLT ? CHECK OUR LISTING FOR SKU# B81F 
IF YOUR OLD CARB HAD STUDS INTO THE CARB BODY THAT IS.
