I ordered 2 engine oil cooler lines for my 1992 k 1500 w/t pickup 4.3 . They were here in 3 days. One line fit perfect & the other was for Totally for something else . Found out it was a Restocked item put in another bag with my part number on it. Useless !!! They said "keep the part & we will send you another" had to wait another 3 days !?!? DUHHHH
