TRNW-2: 10R80 pump bolts

[Steve Everett]

 I've used them a couple times and didn't have any issues,   the very first
10R I built I didn't fully engage one of the clutches in the CDF drum and
we had to pull it back out, I noticed then the silicone on the bolts was
smashed and distorted and basically useless , I had to add silicone to each
when I reassembled it,

     The latest Ford pump bolts are 1000% better than those cheap pump
bolts in the Precision kits,  I'll never use them again,  Ford bolts are
only $1.40 each, and if needed to can easily be reused,   I'm not a fan of
Precision kits anyway, and stuff like this is one of the many reasons,

     As far as the torque to yield stuff they said when these came out, and
is still repeated to this day,  all the replacement bolts I've seen are
steel,  including the cheap ones in the kit I used,   the torque spec is
only 20 ft lbs as far as I looked up,  I doubt very seriously those bolts
are going to stretch at that low of torque ?   in fact I doubt aluminum
bolts would stretch at only 20 ft lbs ?  so some "engineer" who has no
grasp of the real world came up with that when designing this unit
