Putting the 351w together in my 73 maverick so I can run my new wiring and I'm missing some parts. Piecing together v belt pulley system. Got a 3 groove crank pulley that matches my existing w/p pulley and p/s pulley. Groove for alt belt in crank pulley holds the back of the belt flush with the top of the groove but on the 351w alt I got from summit the same belt sits with its back slightly over the alt pulley groove is this ok, the belt still seats fine . Also I am looking for a a/c pulley bracket pedestal does anyone have a part number and a pic would be great. 1st pic (alt belt in crank pulley groove) 2nd & 3rd pics ( alt belt in alt pulley groove) 4th ( a/c bracket pedestal mounting area) 5th (3 groove crank pulley I picked up) 6th (belt system so far)
