Images from the internet show 5R535 and 5R536 with a 66 grill. Assuming an accurate restorations, that will make 6 with a 66 grill. In fact the last batch of 14 R-models all had San Jose start dates of 4-20-65, from 5R527 to 5R540. Again from the registry 5R528 is also noted with a 66 grill and side strip. Making seven confirmed 66 grills. This would suggest all 14 R-models from 4-20-65 got the 66 grill and 66 side stripe. At least half of them did.

George Watters states that 5R528 definitely came with a '66 grill, as shown in this original photo at Waterford Hills:
