I'm doing just fine.
After talking with my brother-in-law, who is a welder by trade, and to the shop I decided that I would accept the used parts.
It's not going to be done until April 21st, at the earliest, and I told them they can go ahead and keep it until I'm back from vacation on April 27th. I'm not going to take a car just out of the shop after major work on a several hour drive to meet up with my sister for our trip.
