Whether you're switching it up and want to swap out colors on your MR30 (now MARG30) or Square Taper crank, or you somehow totally annihilated the set that was in your crank like I have, these kits from White have everything you need to replace your whole crank bolt/extractor assembly.
Each set comes with 4 thin washers to go on each side of the flange on the bolt.
The Square Taper ones do work with some other old non-White Ind square taper cranks, but not all of them, its the most common size as far as I can tell so it should work with most.
