I saw the picture of the stud and it looked like a carb stud. I've always been amazed that people lift an engine with those studs, using a plate made for them. I never did that, I use the head end bolt holes.
Shipping has been driven by the USPS for a long time, and the Sunday Fedex thing, plus Saturdays, is new. The PO began Sunday delivery here a few years ago, but the huge failures of UPS and Fedex a couple years ago changed their businesses.
They had countless failures to deliver parcels right at Christmas a couple years back, they were not equipped or manned to handle the volume increase that year. I had a parcel the myself that UPS could not find when I went there to pick it up, and that was about the 20th of Dec. I went back two days later and they found it.
So this year it seems common to see UPS and Fedex trucks on the roads both on Saturday and Sunday. I received something last Sunday by Fedex, just a normal ground shipped item.
They had to hire more people etc, no doubt, for the holidays. But it looks like they are also adopting the limited deliver on weekends like the PO began in bigger cities. We do all Sundays in Sevierville now, but not in Pigeon Forge.
