Fan with 3 rivets/blade, 2.5" spacer, and 4 bolts.

Part number 9791346 T, second number 913487

date code is B 68 (Feb 1968?).

"...but should be nice to go to a numbers matching March/April/May 1968 non-AC car if I understand correctly?"

The "346" 5 blade flex fans typically do not date original cars that tight. Have personally pulled over a half down original "346" flex fans off original 69 GTO's where the fan predated the car's boy build by 8-10 months. A Feb of '68 dated "346" could have come on one of the first '69 RAIII builds.

The most important issue on any of the factory flex fans is making sure the stainless blades are not bent, or showing the beginning of a crack right outboard of the stamped steel retainer. If the stainless flex fan is damaged in that area it's basically a cheap core. There are several of us who have gone to the trouble of replacing a fan blade on this type of fan.
