Didn't get good news so I spoke to the owner. Long story short, he was PISSED. Apparently, we have gotten bumped back by the shop manager I was dealing with 4 separate times. I won't be surprised if there is a new manager in place next time I visit.
He promised rush treatment and personally told the painter that nothing else leaves his shop until our manifolds do.
I think it is now safe to say for sure that we are close. He promised me a Monday update.
