aftermarket spring question

Probably a good plan. I wonder who makes them for them. Lots of springs listed on Summit's site. They all have different specs. Some have coil bind information and some don't. Hughes is a bit sketchy on their specs. Crazy!
I checked tracking at first it said would be here Monday by end of day and then today and now it's just stuck in transit with no possible delivery date. Covid is really jacking up shipping everywhere.
