As an update.  I received the u bolts from Plattsburgh Spring.  Installed them and they are perfect.  The right size, diameter, length and width.  It took 5 minutes per side to replace both and they look like the truck came with them…minus the rust and literally 64 washers the P.O. had used to keep the original U-bolts.  I was always told that you should never reuse Ubolts as once torqued, they stretch.  I guess the P.O. never heard of that…
 
Plattsburgh Spring was awesome to work with!  Very helpful folks, shipping was quick and they were there with real humans to answer any questions.

I have an update for you all.  After trying all the “normal” stuff that you guys recommended, the winner is...drum roll please...Greg g....  everything checked out OK however compression check results revealed cylinders 1-4 between 100 and 105 psi, cylinders 5&6 - 70 psi.  So apparently there is a dry head gasket leak between the cylinders.  Oil is not emulsified, no exhaust in the radiator.  Ok so all that being said, any recommendations on additional work that should be done when changing a head gasket? Any pointers I should know before digging into this?
 
thanks once again for all the help here!
