I think the '48 has a different set up . Looks to me like the '48 stand has the locator 'knob' on the bottom . The '54 has it on top .
Your '54 is likely similar to my '57 . Here's a pic that shows my kickstand ( left side , just down from center ) . You can see that it attaches opposite the '48 which has the pivot bolt below the locator knob .
