I was changing my starter and i was going back to put the distributer back in and... help me?

its a 1990 honda accord and 0n that kinda car the dist. goes into the head and i was screwing it back in and i cracked the part where the screw goes back in and it i dnt look like the piece i broke off comes out do i need a whole new head|||Take a camera photo of the exact problem in bright sunlight on the part and bring the photo to the Honda or independent shop and ask them. I%26#039;m sure they%26#039;ll have a fix without removing the head.|||JB Weld it
