Friday I bought the lower hose (pn# 7459) from NAPA and although it says it has a spring in it on the webpage it is not true. I asked the sales person and he gave me the same as 4x4Poet got.
One of the reasons (my 2 cents) the lower hose rubs the frame is because people don't take the time to trim the hose as it should be trimmed and it pushes the hose up into the frame. The lower hose on my truck was kinked because the PO did not take the time to trim it. I was going to trim it and reuse it but decided against it and bought a new one.
NAPA hoses are made by Gates.

PN 7459 does not search for the NAPA inhouse sales unless they use 1972 if I remember correctly.
This is information I discovered and believe to be correct. I looked at other trucks, searched webpages, and asked questions. Web information ca be very decieving and incorrect, hence the wire coil in the lower hose. The more information we document the safer we are when we buy these kind of items. Most of the inhouse sales personnel live by the computer though ocassionally you will find a good one that knows parts. Had that kind of experience at Autozone today when I was buying a power steering hose for my DD 1993 S10.
What hoses are the other members using? What is the application: year, AC or not, shroud or not, clutch fan or not, 4-core or not, AT or Std, V8 or I6?
