Timing Cover Screw Thread Size

 Can someone tell me what size thread the timing cover normally has?  I
just bought a 1987 FXR.  It has the factory timing cover, the bottom
rivet is missing.  Rather than re-reveting it, I'd like to drill and tap
it.  I'm thinking 1/4-20, but I don't remember (I had a FXS before).

Thanks,

Dave

  More likely it's 10-24 or 10-32 . Just a hair bigger than a 1/8" pop
rivet ...

Rivets top and bottom attach a faux timing cover to the real timing cover
underneath.

The real timing cover is retained by screws at 3 & 9 o'clock.

The MoCo does not trust you to set your own timing...  :^)
