I have a 72 mark 4 in my Nova . The starter is giving me some problem's . It has a tendency to grind the flywheel on occasion . It is very annoying!The starter bolts are in line with gear . I want to install a new light-weight high-torque starter . The flywheel is 14" 168 tooth and the block looks like it has threads for the new one . Just wanted someone to reassure me everything will work o.k. before I throw down the cash for the new piece.thanks
