Ken, with all due respect, as soon as you made the above statement, most/many of us here knew exactly who you meant.
I think aussie merc made some good points in his post and I thought the same thing as soon as I read your post #1.
By going back to the re builder and letting them know what happened might help the guy in their shop who made this mistake to remember to double check things more carefully, and possibly avoid this from happening again.
On the other hand, by letting us Fordbarners know about that pushrod bushing not being in its proper location, which caused low oil pressure, was educational for many of us here as something to check for, should we be faced with a similar problem of low oil pressure
