Went to install a new fanbelt and it noted the generator bracket is only held on by two of the three mounting bolts The fender side bolts upper and lower are both present but the central upper bolt is missing I believe this bolt mounts into the inlet manifold . I assumed it would be the same as the other bolts ie 3/8-16 but seems to bottom out at an inch and a quarter and the thread won't engage -What is the correct bolt to use here ?? My car is RHD and there is not a lot of room between the bottom of the generator and the steering knuckle -It would be some what problematic if the generator fell down and jammed this at speed !! Thanks Karl
