Hanger pin, rear spring shackle, 20hp 51 in Oa - end of P-series

BCR070 is specified for 20hp chassis GVO11 to 20/25 GWP41 (the end of 'P' series). However it can be used for earlier chassis from GPK31, which had a pin that was not lubricated by internal drillings. The length of the taper on the earlier pin is also shorter, and consequently care will be required during fitting to avoid the taper 'bottoming' before the pin is fully home in its socket.
