since there are so many threads on Pillow bolts I thought I'd put this together. I hope I didn't miss anything??
current pillow bolt:
original bolt before the Pillow was introduced:
pillow bolt with pillow shot out(look at the wear from the detents!!):
pillow bolts with screw on pillow and with QD
for replacement of the pillow I was able to get the pillow and bolt as one piece so I didn't have to uncrew the old pillow to replace with a new one.
