REPAIR KIT, COOLING VANE SPRING WITH CLIPS
Repro Extension spring, plus 1 each, Flat and Bent clips, includes 2 rivets and 2 washers.
Nine out of ten tabs you'll see out there will have already been re-drilled because the springs tear through them.
But are you running out of tab real estate?
Still made of steel, (even if we increased the thickness a little), this is a wear, not a strength problem, so both flat and bent repro spring clips are case hardened.
You can fit and forget about them.
To install, center punch or drill a small starter hole in the old clip's rivet. A number 40 drill is the perfect size to evict the current occupant. Use the AN470 rivets and the washer provided, noting the correct side of the vane and orientation, since these work in pairs.
