Biker John Davies,
Thank you for the picture and the measurements. This is crucial for swap meets. boot sales and other places one is hopeful! Is there any chance you or someone could post picture of how it's mounted? My friend has a SF in the town I live in, however, his tool box was missing and he had to make his. It looks great, but neither of us know how it should have been mounted. It appears form your picture that there is a strap that attaches behind the oil tank and another that goes to a clamp at the lower casting point for the rear plunger. Is there a another anchor? How doe it attach behind the oil tank?
I'm excited about my SF. It has been a decade of parts hunting, but it's slowly coming together.
