1 large port in the rear full vac that i used for the pcv instead of pwr brakes ,I went to the manifold fitting in the back of the intake for brakes,2 small full vac in the front ,1 used for dizzy and the other plugged.
Another small issue was the hold down stud thread for the air cleaner,it was 5/16 instead of 1/4 .
Another clearance issue was I'm using the orig type open element chrome BB air cleaner with the base drop and the crankcase elbow had to be dented in for clearance for the secondary pump arm.
Also mine didn't come with the 3/8 " fuel fittings or filters in the bowls, no base gasket ,maybe if you ask they may be an option but I used the ones off my 770 .
