(if the nut falls off, which is better that loosing the bolt, when the nut falls off, from the top)
Then maybe, because of damage to the bolt (or an important mechanics head) and with ground clearance a consideration, a wise GM engineer (ex Ford)decided that with a castle nut and split pin, the bloody thing can't fall off, "so we will fit them the other way up" (good stories have happy endings)

Lynn thanks for the comment. I can certainly see the logic in your observation and would agree in principle however and given the tubular configuration of the actual mounting I suspect that subsequent operational experience/s convinced some bright mechanical engineer that the optimum location for the spring was on the top.
No doubt an AEME/REME/Canadian Version official notification will surface in due course outlining the reason/s for the change. Always room for another little mystery!! Rod
