Dayco Alternative Belt FWIW - The correct Dayco Poly Rib alternative is 5060875 for a 1997 car. I bought mine at Advance Auto Parts - Their computer cross references the Gates K060863 with a Dayco 5060865 which does not work. I learned the hard way. The last three numbers in the Dayco numbering scheme indicate the overall length. 875 indicates 87.5 inches which is consistent with what others have posted on this site regarding the proper length of the belt. The 87.5" belt is a very tight fit and requires a solid inch of travel of the tensioner There is no way the 86.5" belt would have fit. Good Luck, Don |
