Does anyone know where the distributor body installation bolt is located?

 

some have only one, some have two. The bolts you loosen to adjust the timing are the mounting bolts. They go through the long holes and into the cylinder head.
The directional arrow happens to point to one of these holes.

 

Thanks. So after I loosen the mounting bolts, I just turn the distributor? Please correct me if I am wrong.

 

I don't know what you want to do. Replace it? adjust timing? Just have fun?

 

I want to adjust the timing

 

then, just get them loose and turn it.

 

Of course you need to use a timing light and shine it on the markers. I cleaned my markers and put a little while paint on it. It is pretty tight down there.
