great parts but shipping not so good
I did the 3 day shipping because I needed the parts right away, I checked to make sure the parts were in because it said before I bought them that shipping depends on availability, so it said they were in, I ordered them on the 21 and got them on the 30th, so I paid 3 day shipping for nothing, but still great quality parts, will do business again just not paying for 3 day shipping again.
