rotors off of the 72-73 BBC impala's are 5X4 3/4 and fit the 67-72 spindles. I would take your bearings down to the parts house and check to see if they are the same. I have dropped spindles also but they arent DJM.

Seems like the obvious question is why do you want to go to 5 4/3 bolt pattern?

1.25 is the thickness and you will have many more wheels to choose from with the car pattern. I'm running the impala calipers too.
