<VV> Clutch head screws

[Clark Hartzel]

Beware of trying to remove these screws.  Based on my experience 2/3 of them
will break off and are almost impossible to drill out!  
The only screws I would remove is above the heater box so you can easily get
at the starter motor without having to jack the truck up.  I replaced mine
with normal hex head screws. I welded a support across between the frame
rails to hold up the heater box without having to remove the nuts from
underneath to get the top cover off.
