I am not at home, so can't double check the stubby fuse, but it will be the big power draw.
The black fuse pullers were an optional item, they were not included as a part of the regular tool kit.
I also put one of the 14mm oil plug wrenches in my tool kit. But the drain plug on both the 250 SL and the 280 SL are "outies" with a 17 mm hex head. I think the early cars had the "innies" with the 14 mm allen head screw. The 14 mm plugs are used on the manual tranny and the differential.
Have not tried to source the white fuses, Authentic Classics has the white fuses, but it appears they have the gold metal links.
