The belt diagram shows an alternate route for bypassing the AC on a 1990 Oldsmobile Cutlass Ciera S that I believe has the 3.3L V6 engine. None of the parts stores seem to have it listed. Perhaps it’s available for this engine in another vehicle/model year.

A 6 rib 74.5" long 0.82" wide 0.17" thick belt should work. Dayco part number 5060745 Valucraft/Driveworks part number 745K6 Sources: https://www.a-body.net/forums/showthreadhttps://forums.anandtech.com/index.php?t
