Rear ABS tone ring

[WDW MKR]

Can someone tell me the diameter of the rear ABS tone ring on the GEN3/4 shafts? I had a spare set and sold them before I thought to measure. I know the front tone ring is identical to the GEN2 cars. Need to verify the rear. According to a web search, they are 54-tooth. I'll count mine this evening. More interested in the ring diameter and associated clearance to the wheel speed sensor.
